The Ranque-Hilsch vortex tube is a simple device with no moving parts that is capable of dividing a high pressure flow into two flows of different temperatures.
The CFD simulation of the flow field in a Ranque-Hilsch vortex tube presents challenging task because of its compressibility, turbulence and high swirl.
2014) have conducted an extensive numerical investigation of a double-circuit Ranque-Hilsch vortex tube by applying and testing multiple turbulence models (k-[epsilon], k-[epsilon] RNG, SAS-SST, RSM-LRR and LES) using a three-dimensional model for solving steady state compressible flow in Ansys CFX.
Authors claim that the actual values and CFD model results indicated that CFD model can be successfully used for the determination of heating and cooling performances of curvature effects on Ranque-Hilsch vortex tube.
Kandil, Abdelghany (2015) have presented the results of a computational study of the Ranque-Hilsch vortex tube.
2009) have published the results of the numerical simulations of the internal flow in a commercial model of a Ranque-Hilsch vortex tube operating in jet impingement.
Numerical methods were used to compare the influence of different Reynolds Averaged Navier-Stokes (RANS) based turbulence models in predicting the temperature separation in a Ranque-Hilsch vortex tube.
The vortex cooler, shown in Figure 1, (1) is a tube, also known as the Ranque-Hilsch vortex tube
that separates gas (usually compressed air) into hot and cold streams.
