Boussinesq Approximation

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 the surface of a fluid layer under the action of gravity
  • Turbulence modeling and eddy viscosity: in modelling the turbulence Reynolds stresses, the Boussinesq approximation results in the use of an eddy viscosity concept

The essential idea in the Boussinesq approximation is the elimination of the vertical coordinate from the flow equations, while retaining some of the influences of the vertical structure of the flow under ...
