3 新颖的算法 3.1 数值解的范围 要想使复杂流场的准确数值仿真成功,计算方面的处理方法应该是既强调对流体基本物理规律和力学规律的理解,也注意建立它们的准确模型.计算模型必须基于最少的一组过程和机理,人们认为这些模型能给出已知的分析解和观测结果的主要特点.对每一个主要过程
3 Novel Algorithms 3.1 Range of Numerical Solutions To accurately simulate a complex flow field, the computational approach should be to emphasize both the understanding of the fundamental physical laws of fluids and the laws of mechanics, and the accurate modeling of them. The model must be based on a minimal set of processes and mechanisms that one considers as giving the major characteristics of the known analytical solutions and observations.For each major process
