Numerical and Experimental Investigation into the Effects Combined of Hybrid Nanofluids and Micro-Finned Surfaces on Pool Boiling Heat Transfer Enhancement

The present paper examines the utilization of hybrid nanomaterials, Al2O3 + CuO and ZnO, and micro-fins as compound heat enhancement techniques to maximize pool boiling heat transfer efficiency.Numerical modeling and experimental measurements have been adopted as research methods to identify the heat transfer parameters in a pool boiling process.The utilization of micro-fins increases surface areas and reduces vapor film, whereas Al2O3 nanoparticles with a dispersed arrangement improve thermal conductivity and promote liquid nucleation sites, which also contributes to enhanced heat transfer.An acrylic pool and copper tube are used as pool boiling systems.The pool is 15 15 25 cm without the pool thickness.Nanoparticle hybrid Al2O3 composed of CuO and ZnO is then tested for its thermal and physicochemical characteristics.Thermal discharge from fins experienced a rise with the temperature reaching 34 in water + 0.1 wt% Al2O3+ 0.4 wt% CuO.As well as 35 in water + 0.25 wt% Al2O3 + 0.25 wt% CuO and up to 38.Conclude that nanomaterials have great effectiveness in thermal discharge and the transfer of thermal energy from the fins to the water that contains nanomaterials, as well as improving the condensation process in the pipes.
