Abstract:
The history of CFD (Computational Fluid Dynamics) in China is briefly reviewed in this paper. In 1970s, under the suggestion of Professor Hsue-ShenTsien, some scientists turned their research interests into a new field, Computational Fluid Dynamics. Since then, CFD has become more and more flourished in China. CFD in China has progressed vigorously in this century, and has made significant contributions to Chinese aeronautic/astronautic industry and other civil areas. In China, integrated study of CFD and physical analysis has been advocated since its early stage. In this paper, the concept of M
5A, which contains the main research fields in CFD in China, was reviewed firstly, then the principles to design numerical schemes were introduced. Under the guidance of these principles, a series of numerical schemes were constructed, such as NND, ENN, compact schemes, and so on. Many high-order schemes were developed and applied recently to the complex flow fields over realistic configurations. The criterion of grid size for solving gas dynamic equations was discussed then. And finally, some typical and representative works on flow separation, the flow topology and structure stability, the evolution and Hopf bifurcation of vortex along its axis, the characteristics of dynamic derivatives, and flight stability were reviewed.
