The experimental Performance investigation is carried out for innovative type heat exchanger such as spiral tube heat exchanger (STHE) using Al_2 O_3 nanofluid. The objective of this study is to determine the effects of the variation of mass flow rate of cold fluid and inlet temperature of hot and cold fluid on the performance of heat exchanger in terms of effectiveness, overall heat transfer coefficient, performance index and pressure drop. Working fluids used for experimental investigation are hot water as hot fluid, cold water as cold fluid and Al_2 O_3 nanofluid.
