Abstract:

Vortex tube is a device which is used to separate the energy of a compressible flow of liquid into two streams viz. hot stream and cold stream. In this research paper Computational fluid dynamics (CFD) and experimental studies are conducted towards the optimization of the Ranque–Hilsch vortex tubes on a macro scale. Simulations of more than 20 models of vortex tube were studied and performed; these models included change in length, change in inlet pressure, change in cold orifice diameter, change in cross section of nozzles, change in material of apparatus, number of inlets. Conclusions and inferences were drawn based on maximum cold end temperature difference in the studied models. The obtained computational results for optimum cold diameter (dc), l/d ratio, number of inlet, profile of inlet were validated through experiments.
