Zhang Lühong[6], Zhang Wenqing[7], Feng Cunli[8] and other scientists use the CFD to make the numerical modeling of the distribution of the twin-tangential annular flow gas distributor and the two-line vane gas distributor, and the flow characteristics of the gas distributor is well revealed.
The article makes the numerical simulation of the internal flow field of the twin-tangential annular flow gas distributor and the two-line vane gas distributor, and make the systematic comparison of the gas pressure drop and uniform distribution of these two gas distributors.
The calculation results analysis and discussion The simulation uses air as the fluid medium, and takes the standard k-ε model as the turbulence model, the discretization of the momentum equation, the turbulent Kinetic Energy, and turbulent dissipation rate are solved by using first-order windward scheme.

In this work, we use computational simulations to show there is a transitional region (1 < Re < 20) in between the laminar and creeping regimes for two different micropost array geometries.
We use computational simulations and numerical analysis to better understand the fundamental differences between creeping (Re << 1) and laminar flow (Re > 1) in micro post arrays and identify a transitional flow regime (1 < Re < 20).
A structured mesh was built in ANSYS ICEM CFD 14.5 and element quality was checked using the determinant, angle and aspect ratio as metrics.
Once the CFD simulations were complete, flow profile data was exported into MATLAB for analysis.
Water is a Newtonian fluid, unlike blood, however it is a useful benchmark fluid as it is well-defined and simulating water will allow us to directly compare the simulations to experimental data.

Some numerical simulations are made to investigate on the effects of the tank pressure, docking mechanism and buoyancy.
This paper conducts the research of hydrogen leakage, combining the dynamic mesh technique and the numerical simulation method, in view of the above research situation.
Simulation of hydrogen releases The diffusion area is roughly square in shape with dimensions 2 ´2 m in length and height, using triangle grid, see Fig. 1, the coordinate of leakage face is (-0.1,0).
These kinds of simulations have obtained hydrogen dispersion results and the relative law of dispersion.

Numerical simulation results and related laboratory test are in good accordance, it bear out that researching the It has been demonstrated that it is comparatively reasonable and effective to carry out research on the mechanism of mud membrane formation at a meso-scale level.
Based on the study of particle flow to the characteristics of the mesoscopic medium particle flow and the formation mechanism of mud membrane, numerical simulation of the mesoscopic particle flow was adopted to assist laboratory tests and finally obtained fairly reasonable results.
In order to be compared with the results of laboratory tests, 34 groups of numerical simulations are conducted in 5 different strata, and the specific test groups are shown in Table 3.
In the process of simulation, the calculation results are considered to be stable and then simulation process is over when flow rate of bentonite particles are approaching zero or the change of displacement coordinates are minimum.
The comparison between bore diameter of strata and effective grain size of slurry are adopted in laboratory tests while comparison between particle size of strata soil and grain size of slurry are employed in numerical simulation.
