Abstract
A comprehensive Study investigates thermal performance in a Corrugated Wavy plate heat exchanger utilizing Multi-Walled Carbon Nanotube (MWCNT)-based nanofluids, with a focus on the combined effects of flow-rate, nano-particle concentration, and corrugation angle on efficiency. Experiments were conducted across varying flow rates (2–4 LPM), MWCNT concentrations, phi (∅, 0,0.01,0.03,0.05,0.07,0.09%), and plate angles (0°–60°) to evaluate their individual and synergistic impacts on heat transfer. The results show that an increase in Volume Flow Rate(lpm) increases both heat transfer rate, Q(Watts), and pressure drop (Pascal). Elevating nanoparticle concentration to 0.09% leads to increased heat transfer rate and unwanted pressure drop. Inclination angle markedly influences performance, with optimal(maximal) heat-transfer-rate at 40 ° with optimal(minimal) pressure-drop at 0 ° inclination angle. Corrugated angle, lpm, nanoparticle concentration elevates Q at the cost of pressure drop. An attempt is made to find optimum parameters that enhance the heat transfer rate and reduce the pressure drop. With water as test fluid, maximum HTR is 2060.847W at 30o ° cphe’ angle, at 3lpm. For MWCNT nanofluid as test fluid, max HTR is 2431.613W at 50o ‘cphe ‘angle,4lpm. An 18% increase in HTR is observed. Minimum pressure drop is 7.328871pascal at 0o,2 lpm with water as test fluid, and 7.49995 pascal at 0.01% phi,2lpm at 0 ° corrugated angle with nanofluid as test fluid. Pressure drop almost remained constant for water and 0.01% nanofluid. Optimal response from designxpert software is found to be 7.5pascal pressure-drop,2431.6Watts HTR at 50 degrees, 4lpm,0.01% nanoparticle concentration with 0.7 overall desirability.
