The Numerical Study of Flow through Complicated-Channel with the Lattice Boltzmann Equation Method
Lattice Boltzmann Equation 방법을 복잡한 형상의 채널 유동 해석에 적용하기 위한 수치적 연구
Abstract
This paper deals with the evaluation of several boundary conditions which are commonly used in the lattice Boltzmann equation method. 2-D channel flow(Poiseuille 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.
