| Abstract: | In the grid division of the vane type fluid machinery during CFD numerical simulation stage,it was easy to appear the phenomenon of cavity occurrence when the software of ANSYS ICEM was used for grid generation.Its reason was analyzed by continually changing the mass center position,and the methods of its solution were explored.It was pointed out the key to solve this problem was to properly create a body.How to create properly a body as well as two methods of creating properly a body were elaborated.It was... |
