Full Body Fitted Method with Cartesian Coordinates for Solving Viscous Fluid Flow Problems on Complex Geometries

摘要

A novel body fitted numerical method with Cartesian coordinates for solving the viscous fluid flow is studied in this paper. This method takes advantage of Cartesian coordinates and reserves irregular control volumes near boundaries, so this scheme is full body fitted method. With the boundary cut cells, accurate treatment is carried out which is different from all other Cartesian grids method.
