ON THE RESEARCH OF FLOW AROUND OBSTACLE USING THE VISCOUS CARTESIAN GRID TECHNIQUE

ABSTRACT
A new 2-D viscous Cartesian grid is proposed in current research. It is a combination of the existent body-fitted grid and Cartesian grid technology. On the interface of the two different type of grid, a fined triangular mesh is used to connect the two grids. Tests with flow around the cylinder and aerofoil NACA0012 show that the proposed scheme is easy for implement with high accuracy.
