Numerical Generation of C-Type Cascade Grid in Random Rotating Surfaces
Nuaa Nanjing · Transaction of Nanjing University of Aeronautics and Astronautics · 1995
First attempts to apply elliptic equation of curved surfaces to generating C-type cascade grids. In the generated grids,derivative continuity of grid lines across outer periodic boundaries and inner coinside boundaries,and orthogonality of grid lines at the blade surface,are insured by careful use of boundary conditions. The method of controlling distribution of generated grid lines around the blade surface with that of initial grid lines is proposed.
