Lattice Boltzmann Equation 방법을 이용한 2차원 비압축성 유동 해석에 관한 수치적 연구
The Numerical Study of 2-D incompressible flow with the Lattice Boltzmann Equation method
초록
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.
