Energy separation phenomena of those gases were investigated by means of three-dimensional Computational Fluid Dynamics (CFD) method.
With the gradual deepening of experimental research and numerical simulation calculation, the vortex tube has been applied to many filed such as a lot of compressed gases source, electricity no use or wish less to use, and its requirement less cooling capacity position and played an important role in industry.
The fixed component ideal gas Simulation temperature effect becomes small, and because of the energy conversion, due to the different freedom degrees [10] cause collision loss occurs between the different gases inside the vortex tube.

Ji-Hang Luo [4] takes the rotor blades with three different parts of NACA airfoil as a reference, and uses the main model of commercially available NORDEX plant's N-50 800kW wind turbines as a simulation object.
By using of STAR-CD CFD software for simulation, he compares the wind power, flow and torque under different available wind speeds to find the better airfoil.
This feature is that the use of the wind turbine simulation model to establish the flow field domain model, simulate the operation of wind turbine rotor when the wind load.
In fact the wind machine in the load situation is very complicated, and the actual wind conditions and wind machines are non-stable, so in the simulation of this paper the ideal wind conditions are assumed.

CFD software FLUENT is a mature Fluid Dynamics Analysis of software.
In so doing, fluent in fact acts as a general fluid dynamic simulation module.
In collaborative simulation model, the simulation conditions of FLUENT and MATLAB are determined by the real operating conditions of the current system solution, and therefore the accuracy and credibility of the simulation are substantially improved.
