James G. Oldroyd
James Gardner Oldroyd(25 April 1921 – 22 November 1982[1]) was aBritishmathematicianand notedrheologist.He formulated theOldroyd-B modelto describe theviscoelasticbehaviour ofnon-Newtonian fluids.
Life
[edit]Oldroyd was born in 1921 and educated atBradford Grammar School,andTrinity College, Cambridge.On graduation, during theSecond World War,he worked for theMinistry of Supply.After the war he joined the Research Laboratory ofCourtaulds.In 1946 he married Marged Katryn Evans.[2]In 1953 he became professor ofmathematicsat theUniversity of Wales, Swanseauntil 1965 and head of the Applied Mathematics department from 1957.[2]In 1965 he moved toLiverpool University,becoming head of the Department of Applied Mathematics and Theoretical Physics in 1973 until his death.[3] He died 22 November 1982, and was survived by his wife Katryn and three sons.[1]
Work
[edit]In 1950 he published a paper "On the Formulation of Rheological Equations of State"[4]which has been described as "probably the most important single paper in theoretical rheology"[5]as it established the basic requirements for mathematical models of rheology.[2]For this and other major papers he received international recognition, including the Gold Medal of theBritish Society of Rheology,and a tribute issue of its Bulletin on his sixtieth birthday.[6]
