摘要
CFD has become an indispensable tool for analyzing and designing aircrafts. Wind tunnel testing, however, is still the central player for aircraft developments and CFD plays a subordinate part. In this article, lessons learned from the developments of the unstructured-mesh CFD for aeronautical applications are discussed at the beginning. Then, demands for next-generation CFD are described with an expectation of the daily use of Petaflops computers. A Cartesian mesh approach, as a promising candidate for the next-generation CFD, is discussed by comparing it with the current unstructured-mesh CFD. It is concluded that the simplicity of Cartesian-mesh CFD from the mesh generation to the post processing will be a big advantage in the days of Petaflops computers.
