Heat transfer enhancement technique refers to different methods used to increase rate of heat transfer without
affecting much overall performance of the system. These techniques are used in heat exchangers, Some of the application
of heat exchangers are in process industries, thermal power plant, air conditioning equipment, refrigerator, radar for
space vehicles, automobiles etc. In the past decades several studies on passive techniques of heat transfer enhancement
have been reported. This paper reviews mainly on twisted tape heat transfer enhancement and its design modification
towards the heat transfer enhancement and saving pumping power.
