Experimental investigation of vortex tube and vortex nozzle for applications in air-conditioning, refrigeration, and heat pump systems
… COPs under the same conditions. The ejector motive nozzle throat diameter (motive nozzle restrictiveness) is one of the key parameters that can significantly affect COP. This thesis presents a new two-phase nozzle restrictiveness control mechanism which is possibly applicable to two-phase …

Experimental investigation of an ejector as a refrigerant expansion engine
… the expected nonequilibrium behavior in the motive nozzle, and assuming equilibrium conditions in the other components. A standard vapor compression system using R-12 was modified to test the ejector. Included in the resulting ejector cycle was a hot gas bypass arrangement which was found to …

Measurement of the efficiency of a flashing flow nozzle
… of a flashing flow converging-diverging nozzle was measured. The primary motivation for measurement of nozzle efficiency in this work was to improve the performance of an ejector as a refrigerant expander; previous experimentation has suggested that motive nozzle efficiency is poor. …

Vortex control of two-phase refrigerant flow in nozzles and its application in ejector vapor compression cycles
… is a novel two-phase convergent-divergent nozzle restrictiveness control mechanism which achieves flow control by adjustable nozzle inlet vortex strength. The nozzle can become more restrictive with increasing inlet vortex strength. Vortex control can potentially provide flow control with …
