Influence of Geometry of Twisted Tape Insert on Heat Transfer Augmentation

Abstract

Heat exchangers are commonly used devices in several industrial applications owing to their high performance in transferring the heat from the hot nature to cold nature. Heat exchangers are necessary for saving energy, there are lots of methods implied to increase the thermal performance of heat transfer device by changing the surface of the flow area of the fluids.in most of the methods there is an insertion in the flow passage like twisted tape or blocks to make a disturb in the flow. Mainly these twisted tapes have a vital role in the heat transfer characters. In this present paper the various techniques used in increasing the heat transfer with the insertion of twisted tape and its geometrical influences on the performance of heat transfer were studied and reported.
