The Heat Pump in a Vortex Tube

The Heat Pump in a Vortex Tube

The temperature splitting phenomenon of a Ranque Hilsch vortex tube in which a stream of gas divides itself into a hot and a cold flow, has been identified as a natural heat pump mechanism, which is enabled by a secondary circulation. We have developed an analytical model that quantitatively explain...

Zusammenfassung:The temperature splitting phenomenon of a Ranque Hilsch vortex tube in which a stream of gas divides itself into a hot and a cold flow, has been identified as a natural heat pump mechanism, which is enabled by a secondary circulation. We have developed an analytical model that quantitatively explains the measurements.
