The Numerical Study of 2-D incompressible flow with the Lattice Boltzmann Equation method

Lattice Boltzmann Equation 방법을 이용한 2차원 비압축성 유동 해석에 관한 수치적 연구

This paper deals with the evaluation of several boundary conditions which are commonly used in the lattice Boltzmann equation method. 2-D channel flow(poiseui1le flow) and lid-driven cavity flow was selected as a test problem of this study, because there exist an analytic solution and previous study which could be used for a benchmarking test. It was found that lattice Boltzmann method still needs more considerations of stability and physical consistency, though it could predict the flow patterns both qualitatively and quantitatively.
