Joseph Valentin Boussinesq ( pronounced [ʒozɛf valɑ̃tɛ̃ businɛsk] ; 13 March 1842 – 19 February 1929) was a French mathematician and physicist who made significant contributions to the theory of hydrodynamics , vibration, light, and heat.
6-523: (Redirected from Boussinesq ) Boussinesq approximation may refer to several modelling concepts – as introduced by Joseph Valentin Boussinesq (1842–1929), a French mathematician and physicist known for advances in fluid dynamics: Boussinesq approximation (buoyancy) for buoyancy-driven flows for small density differences in the fluid Boussinesq approximation (water waves) for long waves propagating on
12-618: The advancement of science. Subsequently, this was developed into the modern physics of solitons . In 1871, Boussinesq published the first mathematical theory to support Russell's experimental observation, and in 1877 introduced the Korteweg–De Vries equation . In 1876, Lord Rayleigh published his mathematical theory to support Russell's experimental observation. At the end of his paper, Rayleigh admitted that Boussinesq's theory came before his. In 1897, he published Théorie de l'écoulement tourbillonnant et tumultueux des liquides ("Theory of

30-493: The swirling and agitated flow of liquids"), a work that greatly contributed to the study of turbulence and hydrodynamics. The word "turbulence" was never used by Boussinesq. He used sentences such as "écoulement tourbillonnant et tumultueux" (vortex or tumultuous flow). The first mention of the word "turbulence" in French or English scientific fluid mechanics literature (the word "turbulence" existed in other context) can be found in
