A CFD Application of Surface Morphing for Vehicle Exterior Development 2007-01-0110
To develop vehicle exterior aerodynamics, a CFD surface morphing tool was applied to change the vehicle exterior surface. Morphing is applied to the surface mesh which then is used in CFD simulation to measure the aerodynamic parameters. Three kinds of general surface modifications and results are discussed, and some comparisons are given for analysis. In this paper, the methodology of surface mesh morphing is described, and its implementation in CFD for aerodynamic simulation is analyzed. Utilization of the mesh morphing process to optimize vehicle surface for aerodynamic drag will be the subject of a future study.
