Abstract
In this article, displacement heat transfer and pressure drop in the water-alumina nanofluid medium inside a tube have been studied numerically. In the numerical study, two single-phase and two-phase Eulerian methods have been used. The tube is under constant heat flux and the range of Reynolds number is between 3000 and 9000. In single-phase nanofluid modeling, thermal and flow properties of nanofluid dependent on temperature and volume fraction are considered. The obtained results indicate an increase in the heat transfer coefficient and pressure drop in the nanofluid compared to the base fluid. An increase in the Reynolds number of the volumetric flow will cause an increase in the Nusselt number and the heat transfer coefficient. With the increase in the volume fraction of the nanofluid, the friction coefficient does not change much, but It decreases with increasing Reynolds number. Comparing the results of this numerical study with laboratory results shows that the results of single-phase analysis are closer to the laboratory results.
