In this paper performance characteristics for a Ranque-Hilsch vortex tube are presented. The was of divergent design and optimised both size performance, to be used supply cold air turbomachinery experiments with feed in the pressure range 3.0–7.0 bar, overall mass flow rates 0.05–0.14 kg/s. Optimum fixed parameters selected from literature were: ratio cold-exit diameter inlet internal (0.50); ...

in this study, fluid flow and energy separation in a micro-scale ranque-hilschvortex tube are numerically investigated. the flow is assumed as 2d, steady,compressible ideal gas, and shear-stress-transport sst k-w is found to be a bestchoice for modeling of turbulence phenomena. the results are in a good agreementwith the experimental results reported in the literature. the results show that flu...

In this study, the past investigations of the design criteria of vortex tubes were overviewed and the detailed information was presented on the design of them. Vortex tubes were classified and the type of them was described. All criteria on the design of vortex tubes were given in detail using experimental and theoretical results from the past until now. Finally, the criteria on the design of t...
