Numerical investigation of lid-driven cavity flow based ontwo different methods: lattice boltzmann and splitting method

摘要

Solutions to the Navier Stokes equations have been pursued by many researchers. One of the recent methods is lattice Boltzmann method, which evolves from Lattice Gas Automata, simulates fluid flows by tracking the evolution of the single particle distribution. Another method to solve fluid flow problems is by splitting the Navier Stokes equations into linear and non-linear forms, also known as splitting method. In this study, results from uniform and stretched form of splitting method are compared with results from lattice Boltzmann method. Lid-driven cavity problem at various Reynold numbers is used as a numerical test case.
