Experimental studies of temperature separation and flow field for different geometrical parameters in Ranque-Hilsch vortex tube

Abstract

Experimental studies are performed to investigate the effect of geometrical parameters on temperature eparation and flow field in the vortex tube. Inlet dimensions, cold orifice diameter, length and diameter of ortex tube are the main geometrical parameters taken into account. Experiments show that most of the emperature separation happens near inlet for the length considered. Inlet nozzle with lower aspect ratio gives etter temperature separation. Temperature separation is further increased when convergent divergent nozzle is sed. Flow field studies on different geometrical parameters show that number of helical turns and residence ime increase with temperature separation. Experimental studies on scale effect are discussed.
