A Review Paper Based on Experimental Investigation of Heat Transfer Phenomena in Triple Tube Heat Exchanger with Dimple on Internal Tube and Internal Threaded Middle Tube and its Validation using CFD Analysis

Many heat transfer enhanced techniques have simultaneously been developed for the improvement of energy consumption, material saving, size reduction and pumping power reduction. Triple tube heat exchanger are a typical technique that offers a higher heat transfer increase and at the same time, only a mild pressure drop penalty. This study will investigates the heat transfer characteristics of a horizontal triple tube heat exchanger having internal threaded pipe in the middle & dimples on inner tube. This research work will lead to findings on the effect of triple tube on heat transfer. It is expected from this research work that the applications of CFD and experimental results are nearly equal to same in triple tube heatex changer by providing turbulence in inner tube and spiral movement of fluid in the intermediate tube of the triple heatex changer.
