Large eddy simulation of flow over a porous surface with a parallel and adaptive lattice Boltzmann method

Large eddy simulation of flow over a porous surface with a parallel and adaptive lattice Boltzmann method
Large eddy simulation of flow over a porous surface with a parallel and adaptive lattice Boltzmann method
We present the inner workings of our self-developed dynamically adaptive lattice Boltzmann software AMROC-LBM and apply the code to large eddy simulations that investigate the thickening and perturbance of turbulent boundary layers over rough and permeable surfaces. Besides the fluid mechanical results, the computational performance on large-scale and massively parallel supercomputer systems is also discussed.

Abstract

We present the inner workings of our self-developed dynamically adaptive lattice Boltzmann software AMROC-LBM and apply the code to large eddy simulations that investigate the thickening and perturbance of turbulent boundary layers over rough and permeable surfaces. Besides the fluid mechanical results, the computational performance on large-scale and massively parallel supercomputer systems is also discussed.
