On the Oberbeck–Boussinesq Approximation on Unbounded Domains

2012
We study the Oberbeck–Boussinesq approximation describing the motion of an incompressible, heat-conducting fluid occupying a general unbounded domain in R 3. We provide a rigorous justification of the model by means of scale analysis of the full Navier–Stokes–Fourier system in the low Mach and Froude number regime on large domains, the diameter of ...

Numerical approximations to the Boussinesq equations

2010
A study of the Boussinesq equations in one dimension is presented. These equations describe the nonlinear wave propagation of a free surface under inviscid, incompressible, and irrotational constraints. Physically, they describe the motion of long waves (compared to the depth of the domain) which find applications in oceanography and coastal ...

Models Based on Boussinesq Approximation

2010
This chapter presents the simplest way to handle the Reynolds-averaged Navier–Stokes (RANS) equations by using the Boussinesq approximation to close the system of equations. We also present a wide variety of turbulence models that can be employed using the Boussinesq approximation.

Approximate analytical solution of the Boussinesq equation [PDF]

, 1999
A new approximate solution of the one-dimensional Boussinesq equation is presented for a semi-infinite aquifer when the hydraulic head at the source is an arbitrary function of time. Estimates for recharge, discharge, and elevation of the water table are given.

Approximate Solution of Nonlinear Boussinesq Equation

Journal of Hydrologic Engineering, 2009
This study presents an approximate solution of the nonlinear Boussinesq equation (NBE). The approximate solution of NBE is assumed to consist of space function and the Fourier cosine series which has time-varying coefficients. The space function is very thin and constant in time.
