Abstract
Flow through an interrupted or enhanced heat exchanger passage is complicated and may cause the natural formation f vortices that can enhance local heat transfer by several hundred percent. Vortex-induced heat transfer enhancement exploits this effect through the deliberate generation of large-scale lonitudinal vortices in the flow. In this review of vortex-induced heat transfer enhancement, the theoretical basis for the method is discussed and both active and passive implementations are reviewed. The aim of this survey is to critically review recent progress and to identify research needs in the area of vortex-induced heat exchanger enhancement.
