Heat exchanger is the primary device in the industries where heat transfer is a predominant process. It is a onetime cost equipment and also is durable for longer period of time, thus making it viable for the mass manufacturing industries. The new demanding criteria in this sector have led to many new types of development in heat exchangers. The current research related to the investigations of heat exchange among three fluids, which are at distinct temperatures. An innovative triple coextensive pipe heat exchanger with materials brass, copper and PVC for inner, middle and outer pipes having 30, 60 and 90 mm diameter, respectively, is used for study. The heat exchanger was premeditated and fabricated for investigation. Three fluids such as normal, hot and cold water are taken for the investigation. Distinct flow arrays are pondered for the studies with multifarious mass flow rates. Further the cold water is replenished by three diverse water-based nanofluids such as Cuo, Al2O3 and TiO2 nanoparticles and likened with the cold water arrangement. The nanofluids used for exploration are at various weight concentration such as 0.01, 0.03, 0.05, 0.07 and 0.10 wt%. The emphasis of the present analysis is to enrich the heat exchange ability of concentric heat exchanger using nano-fluids. The temperature distribution pertaining to the various fluids lengthwise of the tube is assessed experimentally with the help of K-type thermocouple for the altered flow arrangements. The effectiveness of the heat exchanger is reckoned for every layout and assessed. The results concluded that heat exchanger effectiveness is exclusive for nanofluids as compared to normal water NHC pattern.
