Abstract

To evaluate flow fields more accurately and use the software more easily

the algorithm for generating two-dimensional grid based on the CAD model of boundaries is investigated. Analyzing the TM method and the WEI Wenli method

and considering the adjacent boundary nodes sliding method as a reference

an improved method(called improved TM-WEI method)for generating body-fitted grid is proposed. Following the developed AutoCAD software

the two-dimensional body-fitted grids can be generated. A comparison of the improved TM-WEI method with TM method and WEI Wenli method shows that the grids generated by the improved TM-WEI method at the boundaries and the interior have better orthogonalitythan TM method and WEI Wenli method with higher accuracy of solution and better convenience of generation.
