基于非结构化网格有限体积的LBM
Unstructured mesh finite volume LBM
摘要
Abstract
A unstructured mesh finite volume LBM is presented.Cell-vertex finite volume method is used to discretize the governing equations.During the discretization in time,there are two-time steps,pseudo-time step and real time step respectively,in which forward scheme is used in former while the second order backward scheme is used in latter.In space,an edge-based flux calculating algorithm is adopted and higher order TVD scheme is utilized to calculate the flux through control volume interface.A strategy of implicit iteration is used for solving discrete governing equations and the second order five-layer Runge-Kutta method is utilized for the solution of variables.The simulating results of 2Dcylindrical-Couette flow and lid-driven cavity flow show that the proposed method is believed to be an effective tool for solving flow pattern of flow domain with irregular boundary.关键词
