A Review on Performance Characteristics of Heat Exchanger with Twisted Tape Inserts and Nano Fluids
Heat transfer enhancement techniques are widely used in various applications such as air conditioning, chemical reactors and refrigeration systems. Therefore several techniques have been promoted to enhance heat transfer rate and to decrease the size and cost of equipment especially the heat exchangers. One of the main tools used in passive heat transfer to create turbulence flow is with the help of twisted tape inserts. The current paper investigates about the different types of twisted tape inserts used in shell and tube heat exchanger in the recent years are studied at the turbulent zone and also about the overall enhancement ratio.
