流动的

The characteristic and difference of flow in porous media between the pseudo-plastic fluids and the expansile fluids was described in detail. The experimental pressure drop measurements were made in a packed bed under a variety of conditions, and the variation of the friction factor with the Reynolds number was obtained. Corresponding to the flow resistance in a nonporous channel, the flow resistance in porous media can be divided into Darcy resistance and Forchheimer resistance as well. The experiment data was divided into Darcy regime, transitional regime and Forchheimer regime in accordance with the Reynolds number.

And some knowledge of grid topology is also introduced. The nucleation of condensative steam in the whole flowing field has been displayed. Furthermore, the characteristic of two-phase complex flow is analyzed. In the stationary blade's passage, the flowing status is stable relatively. The steam expanding is comparatively relaxing and the nucleation area of steam is small. In the moving blade's passage, the expanding of steam is tempestuous relatively because of dual-velocity effect; the degree of condensation of steam is considerably distinct.

Any high Re number flow over bodies consists of three basic flows: the flow with convection-dominant in all spatial directions, the flow with convection-diffusion competition in all directions and the flow with convection-dominant in part directions and convection-diffusion competition in part directions, which is called the interacting shear flow; the features of the three basic flows are different; their simplest conservation equations, i.e. the Euler equations, Navier-Stokes equations and diffusion parabolized NS equations, have different mathematical characteristics; there is a great disparity in domains of the three basic flows and the domains of NS equations are very small. Therefore, adopting Euler-DPNS-NS equation system to analyze and compute high Re number flows over bodies is a logical approach. There exists a mutual examined-complemented relationship of this approach with the usual one of adopting only NS equations.
