On the validity of the Boussinesq approximation in a tall differentially heated cavity with water [PDF]
, 2011 In the present work, the fluid flow and heat transfer inside an integrated solar collector installed on an advanced fac¸ade are investigated. According to Gray and Giorgini [1], the use of the Boussinesq approximation can be considered valid for ...

On the Frequency of Internal Gravity Waves in the Atmosphere: Comparing Theory with Observations
AtmosphereThis paper is devoted to the dynamics of the propagation of non-planetary scale internal gravity waves (IGWs) in the stratified atmosphere. We consider the system of equations describing internal gravity waves in three approximations: (1) the ...

An improved dynamical approximation to Boussinesq equation using Karhunen-Loeve basis
, 1997 Karhunen-Loeve (K-L) basis is used to provide an efficient relatively low dimensional dynamical approximation to Boussinesq equation governing thermal convection phenomena.

The Oberbeck–Boussinesq approximation and Rayleigh–Bénard convection revisited
We consider the Oberbeck–Boussinesq approximation driven by an inhomogeneous temperature distribution on the boundary of a bounded fluid domain. The relevant boundary conditions are perturbed by a non–local term arising in the incompressible limit of the

Thermal convection and the Boussinesq approximation for ideal gases in the light of kinetic theory
A systematic asymptotic analysis of the Boltzmann equation for monatomic ideal gases is carried out under the conditions that the mean free path of gas molecules and the external force are both small, and the results are compared with the Boussinesq ...

A Karhunen-Loève based Galerkin approximation to Boussinesq equation
, 1996 The Boussinesq equation which is derived from the Navier-Stokes equation is approximated by the amplitude equations constructed through the Karhunen-Loeve (K-L) based Galerkin projection.
