Abstract

The flow in a Ranque-Hilsch vortex tube was investigated using turbulence models of different closure levels ranging from linear eddy viscosity over explicit algebraic Reynolds stress to differential Reynolds stress models. Unsteady flow features could be resolved with the differential Reynolds stress model. The results were validated against experimental data reported in part I of this paper and show qualitative as well as quantitative agreement. A detailed analysis of the flow topology as well as unsteady effects is presented.
