    提出了现代流体力学研究需要考虑的若干基本问题,并且在Navier-Stokes方程合理重构和提出符合物理实在的动力学边界条件的基础之上,构造了一个能够大致刻画速度场和压力场2个独立宏观物理量、处于彼此耦合之中的数学物理模型,进而为绕流体最佳型线的数值模拟提供了可能。

    It is proposed several basic problems needed to be considered in modern fluid mechanics research, and upon the base of the reasonable reconstruction for Navier-Stokes equation and dynamic boundary condition according to physical reality, it is constructed as a mathematical-physical model, which can approximately describe the separated and coupled macro physical quantity about velocity field and pressure field. Furthermore, it provide possibility to numerical simulation of streamline body.
