An Experimental Study the Effect of Nanomaterial's, Hybrid Nanomaterial's, and Composite Nanomaterial's on Heat Exchangers

Abstract

This study analyzed the temperatures of the heat exchanger without, and with various levels of Al₂O₃ and CuO nanomaterials as the comparative parameter. It also presents the results of the analysis of the comparison of thermal conductivities, heat transfer coefficients, and overall performance of heat exchangers based on these new materials the study was conducted, checking the influence of nanomaterial TiO₂ inserted in the heat exchanger. Without nanomaterials in the cup, the paper cup had a steady temperature decrease, starting at 40°C and falling to 38.2°C after 10 minutes. The temperature was elevated by 37.9°C, 37.3°C and 36.2°C after 10 minutes in presence of TiO₂ nanoparticles. Even more, the amount of Al₂O₃ with CuO was added to the hybrid material and subsequently transformed into the melting point that is 38.3°C. The temperatures were gradually increased by the hybrid nanomaterials which were to 37.8°C, 36.7°C, where in there was an enhanced heat transfer and cooling. Through hybrid nanomaterial studies, the researchers investigated the temperature in a heat exchanger. There was a reduction of temperature inherent to the hybrid nanomaterials however, the initial temperature was 40°C and thereafter had a decrease to 38.2°C within 10 minutes. In this manner, it was added to the material and temperature dropped to 36.7°C, 37.5°C, 36.2°C, and 34.8°C.
