Nusselt number values for flow in a rotating reference frame are obtained through computational fluid dynamic (CFD) analysis for Rossby numbers Ro ~1-4 and Reynolds numbers Re ~1,000-2,000. The heat-transfer model is first validated according to Nusselt number correlations for laminar, developing flow in circular tubes and by friction factor correlations for fully developed flow in circular tubes rotating at constant angular velocity about an orthogonal axis. The data show heat-transfer enhancement for increasing rotational speeds, as predicted through secondary flows caused by Coriolis forces. Moreover, the heat-transfer enhancement is found to be greater than the resulting increase in friction losses due to secondary flows.
