Abstract

Current research involves investigating the heat transfer and thermal performances of a STHE utilizing MWCNT-Graphene/water HNF concentrations experimentally. MWCNT-Graphene nanoparticles are mixed with water (base fluid) to create different HNF test samples. Ultrasonication method is used to create three samples of HNF’s with volume concentrations of 0.01%, 0.02%, and 0.03%. The tube side (hot fluid) and shell side (cold fluid) volumetric flow rates are the considered variables on which the entire analyses done. The overall heat transfer coefficient, actual heat exchange rate, convective heat transfer coefficient, energy efficiency, and exergy efficiency are the main objective parameters. It is found that for 0.03% volume concentration, maximum enhancement in various thermodynamic performance parameters is observed. The results concluded are the overall heat transfer coefficient improved by 23.14% and 24.65% for the shell and tube side, respectively, energy efficiency improved by 82.36% and 76.92% for the shell and tube side, respectively, and maximum exergy efficiency is obtained at 0.03% volume concentration, it is enhanced by 23.18% for shell side and by 28.47% for tube side, respectively.
