摘要
本文简要回顾了中国的CFD史,早在20世纪70年代,在钱学森教授的建议下,一些中国学者对计算流体动力学(CFD)这一新型学科产生了浓厚兴趣并开始研究。从那时起,中国的CFD逐渐发展繁荣起来,特别是从世纪之交,中国CFD非常活跃,为航空航天和其他民用领域做出了巨大贡献。在中国,特别注重CFD的研究与物理分析的结合。本文首先介绍了M5 A的概念,它概括了中国CFD的主要研究领域;随后,介绍了设计格式的原则,以此原则为指导发展了一系列格式,比如NND格式、ENN格式和紧致格式。最近,发展了一系列高阶精度数值格式并应用于实际外形的复杂流动计算。再后,讨论了求解气动方程的网格尺寸准则。最后,回顾了如流动分离、流动拓扑结构和结构稳定性理论、旋涡沿其轴向演化和Hopf分叉理论、动导数和飞行稳定性等代表性工作。
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 M5 A,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.
