 Abstract
In this paper, a numerical analysis was performed to investigate the effect of the pitch angle of a helical nozzle on the performance characteristics of a vortex tube. Three-dimensional numerical simulation has been performed with standard turbulence model by using FLUENT 13.0. The effect of the pitch angle of helical nozzle was described in term of . A CFD analysis was performed on , , , . In order to realize the influence of on performances of the vortex tube. Computation results were expressed by the graph and radial profiles of axial velocity and swirl velocity. The results showed that which improves energy separation capacity of vortex tube was at , 0.5 and at . Besides, It was confirmed that the results were closely related to axial velocity and swirl velocity.
