| description | The main objective of this paper is to study the effect of inlet gas temperature change on the fluid flow characteristics and energy separation phenomenon within a counter-flow vortex tube. The computational fluid dynamics (CFD) model is a three-dimensional steady compressible model that utilizes the k-ɛ turbulence model in order to analyse the high rotating flow. In this numerical research, different inlet gas temperatures have been used in the modeling in order to analyse the operation of the vortex tube. The results showed that increasing the inlet gas temperature leads to greater temperature separation, as well as greater hot and cold temperature separation. Moreover, it was found that increasing the inlet temperature does not have any significant effect on the stagnation point and maximum wall temperature position. Since
this research concerns increased inlet gas temperatures, an implication of this study can be for vortex tubes to be used in procedures where heating or preheating is required. |
