Investigation of the parameters of a vortex flow inside a Ranque-Hilsch tube

A Unified Approach to the Study of Transfer Processes

“…A fraction, , of the gas is removed as a cold stream from near the axis at the injection end, the remainder at the far end of the tube from near the periphery as a hot stream (Figure 3a). The vortex tube has been proposed as a cheap and simple refrigeration device, and several detailed studies of it have been made (2,14,16,18,19). By using a simplified model proposed by Kowalewicz (13) and applying the basic conservation equations, a simplified analysis of its operation may be carried out which yields results in good qualitative agreement with the experimental observations.…”
