P24 - Fully Resolved Lattice Boltzmann Simulations of Turbulent Flow Through Porous Media
Presenter
DescriptionWe present simulations of turbulent fluid flow through porous media using a parallel lattice Boltzmann method. The model porous medium is constructed with randomly aligned spheres, the arrangement of which is computed with a rigid body dynamics simulation of a sedimentation process. We apply the cumulant lattice Boltzmann method that is well-suited for high Reynolds number flows. Using modern code generation techniques, the program kernels realizing the cumulant collision operators are automatically generated. Better efficiency is achieved by employing statically refined grids in the region of the porous medium. Large scale simulations will be presented using the open source multiphysics software framework waLBerla.
