Enhance the Performance of Heat Exchanger with Twisted Tape Insert A Review

Abstract

Enhancing heat transfer surface are used in many engineering applications such as heat exchanger, air conditioning, chemical reactor and refrigeration systems, hence many techniques have been investigated on enhancement of heat transfer rate and decrease the size and cost of the involving equipment especially in heat exchangers. One of the most important techniques used are passive heat transfer technique. These techniques when adopted in Heat ex changer proved that the overall thermal performance was improved significantly. This experimental works can be taken by researchers on Augmentation Technique such as Twisted Tape. So, Researchers tried to increase the effective s urface area Contact with fl uid to increases the heat transfer rate in the heat exchanger. We tried to enhance the Heat transfer rate with the help of Tw isted Tape insert with Wiry Metallic Sponge and find out the effect of Metallic Wiry Sponge on Flow of Fl.
