performance analysis of radiator- rectangular duct with winglet shapes using glycerol/water mixture –cuo nanofluids

The study’s goal is to create a radiator-like device with fixed rectangular duct winglets that circulate glycerol/water fluids with varying concentrations of copper oxide nanofluids for improved heat transfer and cooling performance under all working situations. hot water enters the rectangular duct at one end, while the cooling working fluid enters at the other. the findings of the experiment are compared with the computational fluid dynamics model of rectangular duct-winglets for glycerol/water, glycerol/water of 0.1, 0.2, 0.3, and o.4% weight of copper oxide nanofluids working fluids at a flow rate of 0.1, 0.2, 0.4, and 0.3 liters per minute. the findings demonstrated that the magnetohydrodynamics effect, which is based on the radiation parameter, increased as the flow through a region’s heat transfer, causing a higher temperature and pressure drop in the glycerol/water-0.3% weight copper oxide nanofluids at 0.3 l/min flow rate. the results of the experimental for glycerol/water with 0.3% wt copper oxide nanofluids at 0.3 l/min flow rate showed that the pressure and temperature drop at reynolds number 5400 were 19.8 kpa and 9.8 °c with its relevant friction factor and nusselt’s number 0.0113 and 12.97 respectively.
