The Boussinesq approximation for buoyant flows

open access: yesMechanics Research Communications, 2022
The aim of this communication is to present a simplified, yet rigorous, deduction of the Boussinesq approximated governing equations for buoyant flows. In order to carry out the core deduction procedure, a simplified version of the manifold asymptotic analyses available in the literature is discussed. The method adopted in this study is focussed on the

On the Oberbeck–Boussinesq approximation for gases

International Journal of Non-Linear Mechanics, 2021
Abstract The Oberbeck–Boussinesq (OB) approximation for a compressible fluid in Benard’s problem geometry is studied. We present a new derivation of the classical and ’extended’ OB models for a fluid obeying the ideal gas state equation by means of an asymptotic limit for vanishing temperature difference. The ‘extended’ OB approximation takes account

ON THE OBERBECK-BOUSSINESQ APPROXIMATION

Mathematical Models and Methods in Applied Sciences, 1996
This paper deals with a derivation (using a perturbation technique) of an approximation, due to Oberbeck8,9 and Boussinesq,1 to describe the thermal response of linearly viscous fluids that are mechanically incompressible but thermally compressible. The present approach uses a nondimensionalization suggested by Chandrasekhar2 and utilizing the ratio ...

Approximate Symmetries of the Boussinesq Equation

Quaestiones Mathematicae, 2003
In this paper we show that all exact symmetries of the linear wave equation are inherited by the Boussinesq type equation with a small parameter as approximate symmetries in any order of precision. We find an approximate integral­ differential transformation of any order of precision, which transforms the Boussinesq type equation into the linear wave ...
