A Detailed Review to Enhance The Performance of Double Pipe Heat Exchanger: Augmentation Technique

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. One of the most important techniques used are passive heat transfer technique or Augmentation Technique
such as Twisted Tape. So many researchers tried to increase the effective surface area Contact with fluid to increases the
heat transfer rate in the heat exchanger. In this research study focus on enhancement of double pipe counter flow heat
exchanger will gives more efficiency with baffle attached twisted tape insert and it has been compared to the simple twisted
tape insert.
