Abstract
Double pipe heat exchanger is an apparatus utilized to transfer the energy between two liquids. To attain high performance of heat transfer rate in small-area passive methods are castoff. The heat transfer rate along the length of the heat exchanger is intended at different mass flow rates of water by experimentally and numerically. FLUENT analysis is conducted with different strips. In this FLUENT analysis, strip having two elliptical leafs at a distance of 50 mm along the length, the major and minor axes are in 2:1 with 1 mm thickness at altered angles between 0° and 180° at 10° intervals are arranged. These two elliptical leaves are having same orientation and same direction toward the length of the strip. Water is taken as a liquid at various turbulent regions in between 5000 and 20,000. From numerical results, increased rate of heat transfer rates is achieved with strip with elliptical leaves having 60° inclinations because of more turbulence and secondary flows are acquired.
