Abstract
The influence of various nanoparticle materials on the performance of flow in a pipe with a uniform heat flux of 10000 W/m2 is studied. The flow was simulated using Ansys 14.5 and two-dimensional governing partial differential equations. The effect of four different concentrations of nanomaterials Al2O3 and hybrid nanomaterials Al2O3–Cu were employed in this simulation. Al2O3 and Al2O3–Cu nanoparticles scattered in water at volume ratio of (0.05, 1, 2, and 3)%. The Reynolds number (Re) ranged from 254 to 1019, and the inlet temperature was 27 °C. It was shown that raising the amount of nanomaterials of Al2O3 in water enhanced some physical qualities while lowering others. As Cu is added to Al2O3 and water, the amount of heat transport is increased when compared to Al2O3 - water or water alone. Furthermore, when the concentration of nanoparticles increases, the Nusselt number (Nu) rises.
