Maximizing heat transfer and minimizing entropy generation in concentric cylinders with CuO-MgO-TiO2 nanoparticles

Heat transfer is crucial because it has industrial uses. A novel type of nanofluids dubbed "ternary nanofluid"is being utilized to boost the ability of conventional fluids to transmit heat since it has a greater heat transfer capacity than solo and hybrid nanofluids. This work investigates the heat transfer capabilities and entropy generation in the cylindrical flow of a ternary nanofluid in the presence of a magnetic field. Minimizing the entropy generation and maximizing the heat transfer of a fluid using ternary nanoparticles (CuO-MgO-TiO 2 ) is the aim of this work. The finite difference method is used by the MATLAB computer program to solve the problem numerically. The results reveal that the entropy generation minimizes in the presence of CuO-MgO-TiO 2 . The heat transfer rate of the fluid increased by 9.9%, 10.8%, and 11.2% on adding TiO 2 , MgO-TiO 2 , and CuO-MgO-TiO 2 nanoparticles, respectively.
