Comparison of Viscous and Pressure Energy Exchange in Fluid Flow Induction

Abstract

The pumping power and efficiency of a jet pump can be substantially increased by introducing a rotating primary flow. The rotating primary causes an energy transfer from the primary fluid to the secondary fluid through a pressure force. Non-rotating jet pumps transfer energy through viscous friction. The reversible nature of the work accomplished through a pressure exchange is inherently more efficient than the nonreversible work accomplished through viscous interaction. This study focuses on the interaction zone of the inducer and specifically on an experimental comparison of viscous and pressure energy exchange.
