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 $\small{k-{\varepsilon}}$ turbulence model by using FLUENT 13.0. The effect of the pitch angle of helical nozzle was described in term of $\small{{\beta}}$. A CFD analysis was performed on \${\beta}
