Solution of turbulent flow in porous media with boundary element method

Detailed numerical scheme for solving turbulence in porous media with the Boundary Element Method (BEM) is presented. The volume and time averaged Navier-Stokes equations are used as a fluid flow model in porous media and the macroscopic k-e model as a turbulence model. The extended BEM, also known as Boundary Domain Integral Method is used to solve the obtained set of partial differential equations, which solves the velocity-vorticity formulation of the governing equations. Some initial examples of numerical computations are presented.

Three-dimensional natural convection in a porous cavity by the boundary element method

3D numerical simulation of convective flow in porous media using an algorithm based on a combination of single domain and subdomain boundary element method is presented. The fluid flow in porous media is modeled with the modified macroscopic Navier-Stokes equations, coupled with the energy and species equations. The velocity-vorticity formulation is adopted, which results in decoupling the computational scheme into a kinematic and kinetic computational parts. Heat and mass flux through the cavity and flow fields are analyzed, focusing on the 3D nature of the phenomena.
