Henri Claude Bénard, (1874–1939), French physicist, best known for his research on convection in liquids that now carries his name, Bénard convection. In addition, the historical surveys of both Tokaty〔G.A. Tokaty, 1994: ''A History and Philosophy of Fluid Mechanics'' (Dover, pp 168–169). ISBN 0-486-68103-3〕 and von Kármán〔T. von Kármán, 1954: ''Aerodynamics: Selected Topics in the Light of Their Historical Development'' (Cornell University Press, Ithaca), pp. 68–69.〕 both acknowledge that Bénard studied the vortex shedding phenomenon later named the von Karman vortex street, prior to von Karman's own contributions. Bénard specialized in experimental fluid dynamics, and the use of optical methods to study it. He was a faculty member at the universities at Lyon, Bordeaux, and finally the Sorbonne in Paris.〔See Wesfried (2006).〕 Bénard defended his PhD thesis at the Collège de France on March 15, 1901 entitled "Les Tourbillons cellulaires dans une nappe liquide propageant de la chaleur par convection en régime permanent". Bénard was elected President of the French Society of Physics (SFP) in 1929, following the presidency of Louis Lumière.〔''Bulletin des Séances de la Société Française de Physique'' vols. 255–271.〕 He was succeeded as President the next year by his friend and former teacher, Jean Perrin. In 1929 Bénard received the Bordin Prize for his work on vortices from the French Academy of Sciences.〔''Comptes Rendus Hebdomadaires des Séances de l'Académie des Sciences,'' vol. 189, p. 1161 (1929).〕 After his death in 1939, his widow received the Poncelet Prize on his behalf, also from the French Academy of Sciences.〔''Comptes Rendus Hebdomadaires des Séances de l'Académie des Sciences,'' vol. 209, p. 918 (1939).〕 A research center of the ERCOFTAC in Lyon is named after him.〔(http://www.lmfa.ec-lyon.fr/Henri.Benard )〕 ==Life and career== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Henri Bénard」の詳細全文を読む スポンサード リンク
