Abstract



Heat exchangers are used in many industrial areas for the purpose of meeting the heat transfer requirement. The widespread use of heat exchangers has led to a number of designs for increasing the heat transfer in the heat exchangers. One of the widely used heat exchanger types is the double pipe heat exchangers. In this study, the effects of nanofluid usage on temperature distribution in double pipe heat exchangers have been investigated
analytically for laminar and steady-state flow conditions at a certain Reynolds number. Alumina based nanofluid with different particle sizes and water were used as heat transfer fluid in the inner and outer pipes and the fluid temperatures were compared with each other for all conditions. In addition that, for this conditions, the analytical results confirmed with the numerical results.
