考虑松弛效应的流体方程研究

Study of the Fluid Equation Considering the Effect of Transient

通过分析热量、质量、动量传递过程的相似性,把热量传播速度为有限的概念推广到扩散方程和Navier-Stocks 方程中,推导了考虑松弛效应的 Navier-Stocks 方程和扩散方程,并就动量传播速度为有限值的概念在多相流方程中的应用价值作了探讨,在无滑移模型上的应用作了具体推导。

In this paper the concept of finite heat transfer was extended to the diffusion equation and Navier-Stocks equation by analysis of the similarity of transfer in heat,mass and momentum.The dif- fusion equation and Navier-Stocks equation considering the effect of relaxation were derived.The value of application of the momentum transfer being finite in multi-flow equation was discussed.And the ap- plication in no-slip model was developed.
