The grid generation technique for body_fitted coordinate system by means of numerical solution of biharmonic equations is studied, then the topical H_type grid and the flow field is generated and simulated numerically, respectively. Through the results of the examples, it is showed that the method presented has a great capability to control the grid space distance and its orthogonality, the quality of grids generated are satisfactory, and it is a very efficient, high quality and wide generality grid generation technique for the numerical simulation of flow fields.
