Abstract

A thermodynamic model has been used to investigate vortex tube energy separation. An equation has been derived for the rate of entropy generation. This equation is used to model the irreversibility term. A Gouy-Stodola type relation is used for the total irreversibility. The exergy-destruction rate and flow availability are estimated. A vortex-tube laboratory unit has been constructed to verify the theoretical analysis. A new approach has been used to optimize dimensions and operating conditions of a vortex-tube using exergy analysis.
