Improving the energetical performance of vortex tubes based on a comparison between parallel, Ranque-Hilsch and Double-Circuit vortex tubes using both experimental and CFD approaches

Research on the prediction model of energy separation effect of vortex tube based on trajectory deflection characteristics and its numerical solution method

“…In addition to the above comparative analysis to optimize the energy separation performance, it is a new research direction to use a large amount of experimental data and intelligent algorithm to predict the performance and optimize the parameters of vortex tube in recent years. Rafiee [ 14 ] compared and investigated the energy separation effects of Ranque-Hilsch vortex tubes, parallel vortex tubes and double loop vortex tubes through experimental and CFD studies. Rafiee [ 15 ] numerically investigated the fire analysis of vortex tubes using the cfd model and the results obtained are in good agreement with the experimental data.…”
