Heat transfer enhancement is a critical and important phenomenon to save energy and cost, reduce size of the systems and protect the environment from the waste energy effects. Passive heat transfer enhancement method is the most used method since it does not require an energy input to the system. Twisted tape, coiled wire, dimpled surface are the most commonly used methods of the passive heat transfer enhancement method. In this paper, a detail review investigation is conducted on experimentally heat transfer enhancement method by many various configurations of the twisted tape. Addition to geometrical properties such as width, pitch, thickness, different processes implemented such as separated from the inner wall, perforated, center-cleared, jagged twisted tapes effects on thermal and hydraulic performance are examined and discussed. It is observed that the use of twisted tape is quite effectively method for heat transfer enhancement in a tube, since it generates swirl flow through the tube and destruct the thermal boundary layer. Moreover, another advantageous of the use of twisted tape is that to supple low pressure drop penalty compared with other inserts. It is concluded that the twisted tape will continue to use to improve heat transfer in energy conversion systems with more effective configurations.
