The flow of incompressible fluid entering into porous medium region from free space region in a circular pipe were analysed in the paper. 本文对圆管内不可压缩流体从自由空间区域进入多孔介质区域的流动进行分析 ,首先分别得到两种区域中充分发展流动的理论解 ,然后对整个区域采用流线迭代法进行数值计算。 更...
9.6 Compressible Fluid Flow One of the most critical differences in compressible fluid flow, as compared with incompressible fluid flow, is that the physical properties of the fluid are dependent on changes in container area, frictional forces along the walls and heat transfer. We will begin our ...
Use the replace function to replace the incompressible pipes with compressible ones, this can be done either per pipe, with the collected pipes or all pipes of the same type. The replace function can be accessed from the collection (icon with green and red arrows) or ...
Thermodynamics of Incompressible and Compressible Fluid Flowdoi:SAE AIR1168/1本节中处理的流体流动是等温,亚音速和不可压缩的.热量增加,流体做功,声速变化和海拔变化的影响被忽略.不可压缩流体是指压力变化不会导致流体密度变化的流体.液体不可压缩的假设不会在计算中引入明显的误差,但气体不可压缩的假设会引入一...
For ideal, non-reacting gas, if Mach < 0.3 then the flow can be considered incompressible. In startified flows like the atmosphere or oceans, we can make the incompressiblility assumption even though the density is not uniform because the density of a fluid particle does not change following...

A unified numerical procedure is proposed as a solver both for compressible and incompressible fluids. The method approaches the MAC algorithm at very high sound speed and continuously approaches the algorithm for compressible fluid with decreasing sound speed. The advection term is treated by a CIP ...
For the relevant case of incompressible fluids, one can refer to the following paper [31], [35], [36]. Now, let's focus on the compressible fluid model. Recently, Gao et al. [10] addressed the space–time decay of higher–order derivatives of strong solutions by using the Fourier ...
in the case of an incompressible fluid predicts an existence of two propagating waves, only one such wave exists when a fluid is sufficiently compressible... SV Sorokin - 《Journal of Sound & Vibration》 被引量: 66发表: 2004年 On the motion of rigid bodies in a viscous fluid We consider...
In this work, we design an explicit time-stepping solver for the simulation of the incompressible turbulent flow through the combination of VMS methods and artificial compressibility. We evaluate the effect of the artificial compressibility on the accuracy of the explicit formulation for under-resolved...
