The formula of a compressible factor was given and the compressible factor was eliminatedsuccessfully by the introduction of ghost field. A general expresion of equilibrium distribution function, isotherm Navier-Stokes equations and the range of equilibrium distribution function which meetsself-map conditions were obtained.
The flowfield for a rotor a blade in hover was computed using an improved dual time method by numerically solving the compressible Euler and Navier Stokes equations on embedded grids.
This technique is a universal method to solve N S equation, suited to other coordinate systems and boundary conditions more complex than ball surface, and may be used in the research of the 3.4 dimension compressible viscous flow.

Compressible navier-stokes equations with density-dependent viscosity
In this paper, a method of calculation of heat-transfer rate for blunt-bodies in the case of hypersonic turbulent boundary-layer is presented. In order to transform the compressible and axisymmetrical turbulent boundary-layer flow to an incompressible and two-dimensional turbulent boundary-layer flow, the Mager - - Mangier transformation has been applied. According to the characteristics of hypersonic, turbulent boundary-layer with favourable pressure gradient, the classical single-parameter represent...
An investigation has been made of non-steady flow of slightly compressible fluid during depletion of stratified porous systems with crossflow through a thin semi-impervious bed lying between two pervious layers. Approximate expressions have been developed for the variation of drawdown distribution in both layers and of influence radius with time, induced by a well discharging constantly from and screening only in the lower layer. These solutions have been verified with field data, and they are very us...
On the basis of the theoretical analysis of the boundary layer and the calculation of the cascade losses by the use of the '' Optimal control technique'', a method of calculation of the optimum velocity distribution on the cascade surface in two-dimensional incompressible steady flow is presented. The mathbd is then extended to the compressible flow on arbitrary surface of revolution. It is proved that the optimum velocity distribution remains to be optimum when it is extended to cascade on arbitrary ...
