Assessment of the boussinesq approximation for buoyancy-driven flows [PDF]
, 2002 The numerical simulation of buoyant flows often makes use of the Boussinesq approximation. This is particularly true when Direct Numerical Simulation is used for the analysis of heat transfer loops or other applications of natural convection flows ...

Weakly Nonlinear Instability of a Convective Flow in a Plane Vertical Channel
FluidsThe weakly nonlinear stability analysis of a convective flow in a planar vertical fluid layer is performed in this paper. The base flow in the vertical direction is generated by internal heat sources distributed within the fluid.

Spectral Jacobi approximations for Boussinesq systems
Studies in Applied MathematicsAbstractThis paper is concerned with the numerical approximation of initial‐boundary‐value problems of a three‐parameter family of Bona–Smith systems, derived as a model for the propagation of surface waves under a physical Boussinesq regime. The work proposed here is focused on the corresponding problem with Dirichlet boundary conditions and its ...

The approximate solutions of nonlinear Boussinesq equation
Journal of Physics: Conference Series, 2016 The homotopy analysis method (HAM) is introduced to solve the generalized Boussinesq equation. In this work, we establish the new analytical solution of the exponential function form. Applying the homotopy perturbation method to solve the variable coefficient Boussinesq equation.
