Investigation of Turbulent Flow Over Two Wall-Mounted Cubes Using LBM
Large eddy simulation (LES) of a turbulent flow over two cubic prisms is performed based on the Lattice Boltzmann Method (LBM). Two wall-mounted cubic prisms are arranged in tandem on the bottom wall of a fully developed turbulent channel flow for a Reynolds number of ReH \(=\) 4000 (based on the centerline velocity, Uc, and the prism height, H). One major objective of the present study is to investigate the typical flow patterns around the cubic prisms and vortex structures in the wake region. Although the flow geometry is symmetric, the wake interaction introduces asymmetric behavior into the instantaneous flow.
