==Education== Stuart was educated Gateway Grammar School, Leicester<ref name="whoswho"/> and Imperial College of Science and Technology, London where he was awarded a Bachelor of Science degree in 1949.<ref name="whoswho"/> He continued his study at Imperial College and in 1953 was awarded Ph.D. on the basis of ''Stability of Viscous Motion for Finite Disturbances''.

==Career== Stuart joined the Aeronautics Division of the National Research Laboratory, returning to join the staff of Imperial College after a few years. He was appointed professor of theoretical fluid mechanics in 1966 and was head of the Department of Mathematics from 1974 to 1979 and 1983 to 1986. He was Dean of the Royal College of Science from 1990 to 1993. He was an emeritus professor at Imperial until his death in 2023.<ref>{{cite web| url = http://www.imperial.ac.uk/college.asp?P=1825| title =Imperial College Fellowship Awards| publisher = Imperial College|accessdate = 2012-03-02}}</ref>

==Research== Stuart is known for his work on nonlinear waves in the onset of turbulence in fluids. He also extended the work of Lord Rayleigh with research into steady streaming in unsteady viscous flows at high Reynolds numbers.<ref name="FRS">{{cite web|url=https://royalsociety.org/people/trevor-stuart-12364 |title=Trevor Stuart |publisher=Royal Society |location=London }} One or more of the preceding sentences may incorporate text from the royalsociety.org website where "all text published under the heading 'Biography' on fellow profile pages is available under Creative Commons Attribution 4.0 International License." {{cite web|url=https://royalsociety.org/about-us/terms-conditions-policies/ |title=Royal Society Terms, conditions and policies |accessdate=2016-03-09 |url-status=bot: unknown |archiveurl=https://web.archive.org/web/20160220093712/https://royalsociety.org/about-us/terms-conditions-policies/ |archivedate=2016-02-20 }}</ref>
