【 摘 要 】

In this paper, a novel heat transfer enhancement mechanism is deployed, which improves the performance of heat transfer using longitudinal vortices generator in weak regions. Instead of plain fine, the fins embedded with vortex generator are used to reduce the fin area. This mechanism generates less drop in pressure with increasing heat transfer fluid flow. Further, this research aims to study the heat transfer over three row plate fin. Further, tube heat exchangers without and without vortex generators of pair different shape mounted behind a tube is studied through computational fluid dynamics model in a wake re-circulation zone. The proposed mechanism is tested through numerical simulation with different span angles for triangular and cylindrical shaped vortex generator for Reynolds number ranging from 400 to 3000.
