【摘要】 为了更精确地求得透平机械的性能,必须考虑粘性力对通流部分气体流动的影响。为此需解Navier-Stokes方程,但这工作量很大。本文运用边界层理论对Navier-Stokes方程作了合理的简化,得出了适于数值法求解的方程组。更多还原

【Abstract】 The effect of viscosity force on the flow in turbo-machinery is a major concern in determing the performance characteristics of a turbine. Tremendous amount of work involved in solving the Navier-Stokes equation would be necessary. In this article, the Navier-Stokes equation is simplified based on boundary layer theory and a modified equation is developed for numerical solution.更多还原
