Abstract

In the present study, 3D CFD simulation of a vortex tube at high operating pressure is investigated. The impact of inlet pressure and cold mass fraction is investigated in terms of the exergy losses within the vortex tube. The results show that the minimum exergy losses occur at cold mass fraction equals 0.5, meanwhile, the exergy efficiency achieves its maximum at cold mass fraction equals 0.9. It is illustrated that friction has a major impact on entropy generation rate near the wall and at the centre of the vortex tube.
