Abstract (2. Language): 
In this paper, effect of energy separation has been investigated by using a Computational Fluid Dynamic technique. The equations have been solved in 2D and 3D compressible and high swirl turbulent model. The effects of thermo- physical and geometrical parameters also have been considered. Different diameters of vortex tube were modeled. The results show that the temperature separation will decrease by increasing the diameter. It was also found that increasing the cold mass fraction reduces the temperature separation and efficiency. An optimum value was found for the cold outlet orifice diameter. All the calculation for finding the optimum parameters are compared with the rate of axial and tangential work and heat transfer in different control volumes.
