The validity of the boussinesq approximation for liquids and gases

International Journal of Heat and Mass Transfer, 1976
Abstract A new method for obtaining approximate equations for natural convection flows is presented. The systematic application of this method leads to explicit conditions for the neglect of various terms. It is shown that this method allows the specification of the conditions under which the traditional Boussinesq approximation applies to a given ...

Buoyancy-driven flows beyond the Boussinesq approximation: A brief review

International Communications in Heat and Mass Transfer, 2021
The well-known Boussinesq (also known as Oberbeck—Boussinesq) approximation is still the most common approach for the numerical simulation of natural convection problems.

Boussinesq-type approximation for second-grade fluids

International Journal of Non-Linear Mechanics, 2005
We derive the equivalent of the Oberbeck-Boussinesq approximation for second-grade fluids. We find that two new nondimensional numbers (in comparison to the Newtonian model) have to be taken into account in order to arrive at the approximation.

Heat transfer of TiO2 − EG nanoliquid with active and passive control of nanoparticles subject to nonlinear Boussinesq approximation

International Communications in Heat and Mass Transfer, 2021
In this study, the buoyancy-driven two-dimensional flow of a nanoliquid past a vertical plate subject to quadratic Rosseland thermal radiation and quadratic thermal convection (quadratic Boussinesq approximation) is investigated.
