Abstract: In this study, computational fluid dynamics was used to calculate the drag coefficient and Nusselt number for oblate ellipsoids placed near the wall. The simulation results indicate that the drag coefficient and Nusselt number increase with increasing particle-wall distance. Compared to the cases in unbounded uniform flow, the maximal relative difference in drag coefficient and Nusselt number are 75.61% and 36.64%, respectively. Thus, the wall has a significant effect on the momentum and heat transfer between particles and fluids.
