摘要:
研究了刻画一维空间中等熵可压流体运动规律的Navier-Stokes方程的泛函分离变量解.利用微分及分裂的方法把泛函微分方程简化为标准的双线性泛函方程并求解此泛函方程,建立了一维等熵 Navier-Stokes方程的几类泛函分离变量解.

Abstract:
The solutions of functional separation of variables to compressible Navier-Stokes equation in one dimensional space are discussed. By virtue of differentiation and splitting method, some functional differential equations are simplified to the standard bilinear functional equations. And by solving these functional equations, several special forms of the solutions of functional separation of variables are obtained.
