Numerical Simulation of Lid-Driven Cavity Flow Using the Lattice Boltzmann Method

This paper presents the simulation of lid-driven cavity for deep and shallow flow using the lattice Boltzmann method. The effect the Reynolds number on the flow pattern at aspect ratio of 0.25, 0.5, 1.5, 4 was studied extensively. The lattice Boltzmann method is one of the most recent simulation techniques based on molecular theory which is found to be a very efficient numerical tool due to its capability to go deeper into the particle's domain, simulating their interaction among groups of particle and relating the parameters back to macro condition. The comparison of the results was made with CFD software, FLUENT version 6.1. Excellent agreement was obtained even relatively with coarse grids applied on lattice the Boltzmann simulation scheme.
