| Abstract: In this research, nanofluids inside a microchannel, under a laminar flow regime, were investigated using CFD tools and the finite volume method with Ansys Fluent software. A corrugated heat absorber microchannel is used with a flat plate. 3% of copper oxide solid nanoparticles suspended in a non-Newtonian Nanofluid. It was obtained from a concentration of 0.5% by carboxymethyl cellulose (CMC) in water fluid. As a result of this research, the pressure drop increases by about 70%. Also, the pressure drop increased, but no significant effect on the results was observed with the change in the height of the microchannel. The innovation is studying the laminar regime non-Newtonian nanofluid of water-carboxymethyl cellulose with a concentration of 0.5% by weight and copper oxide solid nanoparticles with a volume fraction of 1% and 3%, in a sinusoidal and three-dimensional microchannel with non-slip boundary conditions. The goal was to increase heat transfer and it is successful. | ||
