Experimental and Numerical Examination on Heat Transfer Enhancement using Twisted Tapes

Recent years amply of researchers doing research in enhancement of heat transfer by applying passive heat transfer technique. Recently usage of twisted tape insert to increase the heat transfer surface area is the most preferable passive technique followed by numerous researchers. To increase the complexity of the situation and properly implement the heat transfer enhancement method creating geometrical changes on the twisted tape is leading to a various study of flow physics. In this present review enhancement of heat transfer using insertion of twisted tape investigated numerically and experimentally is reported based on the past decade researches. This review will enable the researchers to involve in diversified usage of twisted tape inserts in the flow field to report the flow physics in detailed manner. This review depicts the findings of experimentally and numerically investigated research works of influence of twisted tape inserts on heat transfer enhancements.
