Comprehensive Review on Double Pipe Heat Exchanger Techniques

The heat exchanger is a thermal device use for heat exchange between higher fluid temperature to lower fluid temperature. Growing need to improve the heat exchangers effectiveness and develop a broad range of investigations for enhancement heat transfer rate along with minimizing the size and cost of the industrial apparatus accordingly. The purpose of the present work to review the articles that related to major types of double pipe heat exchanger and factor effect on heat transfer rate and pressure drop the double pipe heat exchanger considers one of the apparatuses which are used in among industries. Researchers proposed several models of double pipe heat exchanger heat exchangers. Double pipe heat exchangers are used in many industrial processes, cooling technology, refrigeration device, sustainable energy applications and another field. Different classification of Double pipe heat exchangers includes parallel, counter and cross flow. Research operate were also conducted to improve the effectiveness of Double pipe heat exchangers by using turbulators, inserts, rips at both ends, modifying the geometry of channels, methods of injection fluids and, etc. This study reported various research works of Double pipe heat exchangers research works in a technique to satisfy the right effectiveness deciding parameter.
