摘要: In this paper, an analytic method is applied for the generation of 3D mesh system in order for Navier-Stokes equations around ATP (Propfan). One of the advantages of this method is that mesh lines have strong differentiability. The differential equation used is Poisson type and the right hand side is called control function, and this is able to control the degree of mesh line clustering. Here, the form of control function was contrived to cluster near the solid surfaces. By this method, several mesh lines are laid in the boundary layer above the blade surfaces.
