Abstract

A multi-relaxation time lattice Boltzmann method (MRT-LBM) fluid flow analysis code is developed based on a two-dimensional D2Q9 lattice model and sub-grid eddy viscosity model of Smagorinsky. Benchmarking of the MRT-LBM is performed for a turbulent flow over staggered tube bundles at Reynolds number of 18,000and compared with standard k- turbulence and large eddy simulation (LES). The accuracy of the present MRT-LBM with respect to the mean velocity profiles is found to be reasonably acceptable and even comparable to the LES whereas the computational efficiency is superior.
