Abstract
In the present paper a three-dimensional numerical code for simulation of porous
media flow is presented which is based on the Boundary Element Method (BEM).
The most general mathematical model is used to describe momentum, energy and
solute transport in porous media which are based upon the general Navier–Stokes
equations valid for the pure fluid flow. The developed numerical algorithm enables
detailed investigation of the fluid flow together with heat and solute transfer under
various conditions given with different governing parameters, e.g. thermal and
solutal Rayleigh numbers, Darcy number, Lewis number, buoyancy coefficient. In
the paper the effect of different governing parameters on the rate of heat, solute and
momentum transfer are investigated.Under a certain range of parameters, complex
flow patterns occur which exhibits the importance for us to investigate the problem
in three dimensions.
Keywords: porous medium flow, simultaneous heat and solute transport, Boundary
Element Method, Brinkman-extended Darcy formulation.
