摘要：
Enhancing heat transfer mechanisms are used in many industrial applications like heat exchanger, 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 leading tools used in passive heat transfer methods mainly at turbulence flow is twisted tape inserts. The current paper acclaims that want to review experimental researches done on this technique in recent years at the turbulent zone and with respect to the overall enhancement ratio pick the most efficient type of twisted tape.
