The Newtonian flow behavior with relatively high viscosity is assumed for each fluid and used in the simulation with a commercial CFD code (ANSYS FLUENT).
Firstly, the finite volume method divides the domain into many CFD cells.
Then the governing equations are integrated over all CFD cells (control volumes).
The results of the simulations at the location of the MCP for the f1 fluid are illustrated in Fig. 3b.
It is seen that the interface behavior is not affected by the width of the tapes, and this can be used to reduce the simulation domain to have less computational efforts.

CFD can be used to predict operation rule of air curtain used in the cold store intuitively and modelling is the most important part of numerical simulation of air curtain used in the cold store.
Computational fluid dynamics, CFD has become an effective tool to study the air curtain because the air flow field and temperature field are difficult to measure when the air curtain is working because CFD can be used to analyse physical phenomena including fluid flow and heat transfer, and the air flow field and temperature field of air curtains can be simulated visually and quickly by CFD.
Conclusions were drawn as follows by comparing the simulation results and experimental results: (1) The simulation results predicted by the standardmodel were better than those predicted by the RSM through the comparison of the simulation results and experimental results.
Proficient in CFD engineering simulation and case of actual combat[M].

Abstract.
Treating the flow problem in view as two dimensional flow case, since their result will be used as a comparison purposes with the CFD code which currently under development.

Use of CFD for simulation of turbulent flow in stirred tanks can generate useful data to study flow behavior, circulation patterns, vortex structures, etc.
In this paper, we present CFD simulations for flow field in a fully baffled vessel stirred by a pitched blade turbine.
Geometry of the model CFD simulations were performed in a T=0.124 m i.d. cylindrical tank that was filled with Chinese herbal medicine water extract(ρ=1025 kg•m-3, μ=2.2×10-3 Pa•s) up to a height of H=0.1 m, equipped with a three-bladed 45°pitch blade impeller and four baffles.
