摘要: 在黏性流体力学的历史发展中,Navier-Stokes (NS)方程组的 简化理论、相应算法和应用构成了不同历史时期的学科前沿、核心内 容的应用热点。以此为线索,简要评述经典边界层、多层(三层)边界 层、干扰边界层、扩散抛物化(DP) NS方程诸理论、相应算法和应用的 若干研究进展;诸理论之间以及他们与实验的关系;简化湍流计算的 一点注释以及物理分析和数值模拟相结合的一些问题。Abstract: In the course of development of viscous fluid dynamics, the simplified theories of the Navier-Stokes (NS) equations, corresponding algorithms and applications form the frontier and the core of viscous fluid dynamics in different historical period. With that point in mind we review here some advances in the classical boundary layer, multilayer boundary layer (triple deck), interacting boundary layer and diffusion parabolized NS equations theories and corresponding algorithms and applications. The relationship between those theories and experiments, a note to simplifying calculation of turbulent flow and some problems of combining numerical simulation with physical analysis are also reviewed.
