چکیده مقاله

In this work, the effect of performance parameters on energy separation and refrigeration of vortex tube are investigated numerically. The study was conducted on hot-tube length and cold diameter. The three dimensional model is investigated at steady state condition then the RNG  turbulence model utilizes for determining the flow and temperature fields. The finite volume method base on Computational Fluid Dynamic (CFD) model is verified through comparison with experimental data and numerical results used in a straight vortex tube, reported work in the literature. The code was then utilized to study the effects of hot-tube length and cold diameter on the performance of the straight vortex tube. Numerical results indicate that energy separation can be improved by changing these performance parameters and more details are reported during this simulation with contour plots and solid arguments comprehensively. The actual values and numerical sim
