Abstract

This work is concerned with the vortex structures of two-dimensional elliptical cylinder by lattice Boltzmann method. It is known that, the nature of the flow past cylindrical obstacles is very complex. Therefore, in the present work a kinetic based approach, namely, lattice Boltzmann method is used to compute both for steady and unsteady flows. A two dimensional nine-velocity square lattice (D2Q9) model is used in the present simulation. Effects of blockage ratio, Reynolds number and channel length are studied in detail. Here we conclude that lattice Boltzmann method can be effectively used to capture vortex shedding and other features.
