Abstract
The presented study examines the energetics of confined fluid flow in a rotating reference frame. Parallels are drawn to the corresponding scenario of rectilinear motion, where ejection of fluid results in linear propulsion of the frame. Absorption of flow energy into the frame motion leads to cooling of the ejected fluid. Relevance of the observed energetics to the temperature separation phenomenon in Ranque-Hilsch vortex tubes is discussed.
