Optimization of Heat Flow Parameters of Corrugated Plate Heat Exchanger with CuO Nanoparticle/Water as Working Fluid

The research focuses on the thermal performance of Wavy Corrugated Plate Heat Exchangers (WCPHEs), which offer superior heat transfer capabilities and more efficient heat recovery than conventional flat designs. A comparative study of heat flow parameters at different corrugated angles is done. The study focuses on and emphasizes the effect of 0 °,30o, 40 °, 50 °, and 60 ° corrugation angles. Less research has been conducted regarding the impact of corrugated angles on thermal flow parameters of nanofluids. This study experimentally investigates the optimal angle with CuO nanofluid exhibiting enhanced thermal conductivity and minimal pressure drop. A comparative study of heat flow parameters at different corrugated angles is carried out.<br /> Due to their effectiveness, these exchangers are commonly used in pharmaceuticals, brewing, dairy, and food processing sectors. The corrugation is the key geometric factor influencing heat transfer due to enhanced surface area and the ability to promote flow turbulence. Experimental investigations were carried out by varying corrugation angles from (0° to 60°) and flow rates (2,3,4 lpm) and Copper Oxide nanoparticle concentration in water (Ф). An attempt is made to find the optimum condition for maximum heat transfer coefficient and minimum pumping power. Maximum convective heat transfer (W/m2 K) is 4004W/m2K at 50 ° angle,0.09 phi, at 4 lpm. The corresponding convective heat transfer using water under the same conditions is 1686.62/m2K. The percentage increase when compared to a flat plate (0 °) is 110%. Pumping power (pressure drop) in pascal is minimum at 2 lpm flow rate at 0 and 0 phi. Minimum being 7.3Pa at 2 lpm. And maximum 58Pa at 40,60,4 lpm,0.09 concentration. Using MINITAB software, the optimum parameters that strike a deal between the coefficient of convective-heat transfer, pressure drop were noted to be 40,4 lpm,0.05 concentration with ‘h’ equal to 3196/m2K and pressure drop equal to 42Pa.
