Onda di Kelvin
L’ onda di Kelvin è unonda delloceano o dellatmosfera che bilancia la forza di Coriolis terrestre rispetto a un bordo topografico come una linea di costa o una guida donda come lequatore. Una caratteristica dellonda di Kelvin è che essa è non-dispersiva, cioè la velocità di fase delle creste donda è uguale alla velocità di gruppo dellenergia del moto ondoso a tutte le frequenze. Questo implica che essa mantiene la sua forma nel tempo mentre si muove lungo la direzione della costa. In dinamica dei fluidi, unonda di Kelvin è anche un modo di perturbazione a lunga scala di un vortice nella dinamica di un superfluido; in contesti di derivazione meteorologica o oceanografica, si può assumere che la componente meridionale della velocità si annulli cioè non cè flusso in direzione nord-sud, rendendo così molto più semplici le equazioni di continuità e della quantità di moto. Londa prende il nome da lord Kelvin che la studiò per primo.
Medaglia e Premio Kelvin
La Medaglia e il Premio Kelvin sono un premio assegnato dallInstitute of Physics. Fu istituito nel 1994 e prende il nome da Lord Kelvin. Il premio è assegnato ogni anno per premiare coloro impegnati nella divulgazione della fisica che dimostrano contributi eccezionali alla comprensione pubblica della fisica. Da non confondere con la "Kelvin Gold Medal" Medaglia doro Kelvin - assegnata da un gruppo di Presidenti dellEngineering Institute)

William Thomson, I barone Kelvin
Lord William Thomson, I barone Kelvin, comunemente noto come Lord Kelvin, è stato un fisico e ingegnere britannico. AllUniversità di Glasgow compì importanti lavori nellanalisi matematica dellelettricità e della termodinamica, e diede un ampio contributo per unificare lemergente disciplina della fisica nella sua forma moderna. È conosciuto per aver sviluppato la scala Kelvin, che misura la temperatura assoluta. Il titolo di Barone Kelvin gli fu conferito per merito delle sue scoperte, e deriva dal fiume Kelvin, che scorre presso la sua università scozzese di Glasgow. In seguito fece carriera come ingegnere ed inventore del telegrafo elettrico, che gli procurò una maggiore considerazione da parte dellopinione pubblica e gli assicurò fama e ricchezza.
Instabilità di Kelvin-Helmholtz
L’ instabilità di Kelvin – Helmholtz è un tipo di instabilità fluidodinamica che si presenta quando i diversi strati di un fluido sono in moto relativo gli uni rispetto agli altri. Fu scoperta e studiata da Lord Kelvin e da Helmholtz, e successivamente anche da Rayleigh. Lesempio più semplice che si può concepire, in due dimensioni, è quello di due fluidi ideali con interfaccia piana e differenza di velocità uniforme. Se linterfaccia che separa le due regioni subisce una piccola perturbazione, particelle di fluido che erano a riposo cioè con velocità nulla si vengono a trovare nella regione dove regna una velocità finita e viceversa. Questo scompenso crea uninstabilità: lampiezza della perturbazione diventa sempre più ampia le particelle delle due diverse regioni si mescolano tra loro, formando dei vortici e facendo perdere definitivamente la configurazione che era presente allinizio. Una configurazione come quella appena descritta, in questo caso semplice, è sempre instabile, per quanto piccola possa essere la perturbazione iniziale. Linstabilità di Kelvin – Helmholtz si manifesta anche lungo le interfacce dei fluidi ascendenti e discendenti nellinstabilità di Rayleigh-Taylor. Situazioni più complesse e realistiche sono anchesse soggette allinstabilità di Kelvin – Helmholtz, e possono essere studiate: si può prendere in considerazione leffetto della viscosità del fluido, di una densità non omogenea, della tensione superficiale, della gravità, di un campo magnetico, ecc.

Kelvinbridge is the common name of the Great Western Bridge, a cast iron road and pedestrian bridge located in the West End of the city of Glasgow, Scotland, built to carry the Great Western Road at a high level across the River Kelvin. Completed in 1891 by Bell & Miller, it replaced an older stone bridge, and has a similar design to the Partick Bridge crossing the same river, located a short distance to the south-west. It has been a Category A listed structure since 1986. In the early 19th century, the first Great Western Bridge 1825 provided a crossing point across the boundary of the city and into the neighbouring burgh of Hillhead, which was incorporated into the city later. It was at a low level, whereas the second, larger bridge was built over a high span. The river lends its name to adjacent places at several points along its course and so there are several Kelvin Bridges, including one several miles away in Torrance. Adjacent to the bridge is Kelvinbridge subway station on the Glasgow Subway - one of the deepest on the circuit due to the proximity of the river - on the south east-side of the bridge. This was also the location of Kelvinbridge railway station on the Glasgow Central Railway. Due to these other uses, the name Kelvinbridge is also used to refer to the residential areas in the vicinity of the bridge, encompassing parts of the neighbourhoods of Woodside, Woodlands, Kelvinside and Hillhead. The Glasgow Academy private school is nearby on the Hillhead side of the valley, with Lansdowne Church 1863 - featuring a spire which at 66 metres 217 ft is among the tallest structures in the city - on the opposite bank. Due to the proximity of the University of Glasgow, the Kelvinbridge locality accommodates many students.
Kelvindale is a district in the West End of the city of Glasgow, Scotland. Kelvindale shares the postcode G12 with the neighbouring districts of: Kelvinside, Hillhead, Hyndland, Dowanhill and the University of Glasgow. The area is characterised by traditional interwar housing, formed of tenements and semi-detached houses.
Kelvinside is a district in the Scottish city of Glasgow. It is situated north of the River Clyde and is bounded by Broomhill, Dowanhill and Hyndland to the south with Kelvindale and the River Kelvin to the north. It is an affluent area of Glasgow, with large Victorian villas and terraces. As with Morningside, Edinburgh, residents are sometimes said to have a "pan loaf" accent, i.e. an affected one. This often leads to jokes about a "Kelvinsaide" accent. Both of these areas were featured in an advert for ScotRail. Kelvinside railway station was on the Lanarkshire and Dunbartonshire Railway, but is now closed. Kelvinside is home to Kelvinside Academy, a private school situated on the corner of Kirklee Road and Bellshaugh Road. At the corner of Kirklee Road and Great Western Road is a shop called Churchills. Churchills began life as a green hut just a little bigger than an average-sized garage. It was known by locals as the "Greenie". In the 1990s it was replaced by a new two-storey stone building, with a flat in the upper floor and a shop on the ground floor. Although clad with brown stained wood, it is still referred to as the Greenie. The local Church of Scotland parish churches serving Kelvinside and parts of adjacent areas are Kelvinside Hillhead Parish Church and St. Johns Renfield Church. The local Roman Catholic church is St. Gregorys.
North Kelvinside is a residential district of the Scottish city of Glasgow. It is usually regarded as a subdistrict of Maryhill, sharing its G20 postcode, as well as its House of Commons electoral constituency prior to incorporation into Glasgow North in 2005. However, North Kelvinside was never a part of Maryhill Police Burgh prior to its incorporation into Glasgow in 1912 and the area is markedly different socially and architecturally. North Kelvinside was originally part of a country estate, which became enveloped by the surrounding city. As a result, many buildings date from the early twentieth century. It is located on the northern edge of Glasgows west end and its southern boundary is marked by the River Kelvin. It is close to the Glasgow Botanic Gardens, the former BBC building on Queen Margaret Drive, and in the vicinity of the University of Glasgow, although all are actually outwith the North Kelvinside area itself. Being close to Glasgow University many students and academics live in the area. Kelvinside House was the property of Lord Provost Sir James Campbell, and was located in the area that is now North Kelvinside. It was there that his son, the future Prime Minister Sir Henry Campbell-Bannerman was born 1836. North Kelvinside is not directly north of the more upmarket area Kelvinside, which is mainly located to the west. Rather, the area is so named because it is located on the north bank of the River Kelvin. The housing consists mainly of tenements, although there are also some grander villa-type buildings, converted Victorian townhouses, pre-industrial cottages and a small, well-maintained now mainly ex-council estate. The area has a reputation for being quiet and tranquil, despite its central location. Unusually, it is impossible to fully traverse the district by car in any direction, due in part to a system of road-blocks designed to combat ratrunning. Architecturally significant buildings in the area include the Kelvin Stevenson Memorial Church by J. J. Stevenson, 1898; Gillespie, Kidd & Coias St. Charles Parish Church 1959, noted for its hyperbolic paraboloid concrete roof and Stations of the Cross sculptures by Benno Schotz; and the unique Mackintosh Church at Queens Cross, the only church designed by Charles Rennie Mackintosh. Another local landmark is Alexander "Greek" Thomsons Sixty Steps 1872. Contemporary published sources suggest that the steps, associated retaining wall and the original Queen Margaret Bridge were actually part of John E. Walkers co-ordinated civil engineering works of 1869/1870 to the designs of Ritchie Rodger C.E. in preparation for the development of the suburb. North Kelvinside also contains the former pub where the famous balcony scene in the film Trainspotting was shot, the beautiful Kelvin walkway along the banks of the eponymous river, linking Kelvingrove Park and the Botanic Gardens, and a row of small independent shops and cafes, including the long-established North Star, on Queen Margaret Drive, the areas main thoroughfare. Outdoor amenities include the North Kelvin Meadow and the Childrens Wood, which form a popular green space used by all ages. The area is also within easy walking distance of the numerous shops, pubs and restaurants on Great Western and Byres Roads. Famous current or former residents include former Prime Minister Sir Henry Campbell Bannerman, the actor Robbie Coltrane, the comedian Stanley Baxter, director Lynne Ramsay, screenwriter and playwright Peter McDougall, members of the rock band Teenage Fanclub, TV interior designers Justin Ryan and Colin McAllister, Ian Davidson MP and former Maryhill MP, Maria Fyfe. There was a North Kelvinside Secondary School that served most of the Maryhill district of Glasgow. However, the school was closed and the vast majority of the pupils transferred to Cleveden Secondary School in the Kelvindale area on the other side of the River Kelvin to the west. Former famous pupils include: actor Robert Carlyle and musician Jimmy Somerville as well as Janis Sharp; mother of Gary McKinnon. The area is served by North Kelvinside Parish Church, a Church of Scotland congregation which was made famous after World War II, by the work and writing of its minister Rev Tom Allan, particularly his book The Face of My Parish. However, in recent years, the church building was demolished, leaving only the halls which are now in poor condition. The congregation has also been in sharp decline and is currently uniting with the nearby Ruchill Parish Church. Just south of the area is Hillhead, which forms the heart of Glasgows West End, and to the north is Maryhill. To the west are Kelvindale and Kelvinside, and to the east Firhill and Woodside. The district, along with Firhill and Murano Street Student Village, is served by North Kelvin Community Council.
Glasgow High Kelvinside

Kelvinator was a United States home appliance manufacturer and the namesake of the company, although as a company it is now defunct, the name still exists as a brand name owned by Electrolux AB. It takes its name from William Thomson, 1st Baron Kelvin, who developed the concept of absolute zero and for whom the Kelvin temperature scale is named. The name was thought appropriate for a company that manufactured ice-boxes and domestic refrigerators.
Nash-Kelvinator Corporation was the result of a merger in 1937 between Nash Motors and Kelvinator Appliance Company. The union of these two companies was brought about as a result of a condition made by George W. Mason prior to his appointment as CEO of Nash. Nash-Kelvinator ranked 27th among United States corporations in the value of World War II production contracts. In 1955, Kelvinator introduced the Kelvinator Food-A-Rama Side by Side Refrigerator, one of the earliest modern side-by-side frost-free refrigerators. Kelvinator consumer products, before and after the merger with Nash, were considered an upmarket brand of household appliances. In 1954, Nash-Kelvinator acquired Hudson Motor Car Company of Detroit, Michigan, in what was called a mutually beneficial merger which formed the American Motors Corporation. Kelvinator continued as a wholly owned division within the new company. The Kelvinator brand was sold to White Consolidated Industries in 1968, which brought the product under its corporate appliance group, joining the White-Westinghouse, Gibson, and Frigidaire appliance brands. The appliance division of White Consolidated Industries is now part of Swedens Electrolux Corporation. The Kelvinator brand is applied to household appliances and scientific refrigeration systems.
SS Lord Kelvin
The British SS Lord Kelvin was a cable-laying ship which served during the Second World War. Initially owned by the Anglo-American Telegraph Company, Lord Kelvin was completed in 1916. Sold the same year to Transatlantic Cables, the ship spent the rest of her life laying cables until taken out of service in 1963 and broken up in 1967.
The River Kelvin is a tributary of the River Clyde in northern and northeastern Glasgow, Scotland. It rises on the moor south east of the village of Banton, east of Kilsyth. At almost 22 miles long, it initially flows south to Dullatur Bog where it falls into a man made trench and takes a ninety degree turn flowing west through Strathkelvin and along the northern boundary of the bog parallel with the Forth and Clyde Canal.
Kelvinhead is a small hamlet in the vicinity of the village of Banton in Scotland. Located close to the source of the River Kelvin, it is little more than a collection of a few houses along the A803 road between Kilsyth and Banknock. Kelvinhead reputedly, the place where the first crops of potatoes were grown in Scotland. Kelvinhead is a unique location providing access to a core network path to the valley of the Kelvin. The forth and Clyde canal is easily accessible which provides Hiking, Cycling and fishing. North is the path of Banton Loch and Kilsyth hills.
