Experimental investigation of vortex tube using natural substances

An experimental investigation is carried out on Ranque–Hilsch vortex tube (RHVT). Influential parameters such as L/D ratio, cold mass fraction, inlet pressure etc. are investigated. Further, three different working media (air, nitrogen and carbon dioxide) are also tested. An in-house facility is developed to test the vortex tubes. A value of cold mass fraction is observed at which vortex tube performs optimally at the given pressure and L/D ratio. It is found that vortex tube performs better with carbon dioxide as working fluid.
