HEAT TRANSFER AUGMENTATION IN TUBE IN TUBE TYPE HEAT EXCHANGER USING WIRE COIL INSERT

MECHANICAL ENGINEERING

The present review paper is on the performance of tube in tube type heat exchanger with different types of inserts. Heat exchanger are widely used in many mechanical industries, power plant etc. it is required to optimize the performance of heat exchanger. Therefore augmentation technique is used which include active, passive and combine technique. The passive technique is widely used because it is not required extra power. In passive technique use twisted tape or wire coil which is placed in flowing fluid tube then turbulence will create. Then laminar flows gets convert in to turbulent flow which result increases in heat transfer rate.
