摘要：

The flow and heat transfer models of laminar flow and turbulent flow in rolling motion are established theoretically and modified with CFD results and experimental data. The correlations of frictional resistance coefficient and Nusselt number in pipes in rolling motion are obtained. The effect of rolling motion on the flow and heat transfer is mainly affected by the Reynolds number, angular acceleration and channel diameter. As the channel diameter is small, the effect of rolling motion on the flow and heat transfer is weak. The modified correlations of frictional resistance coefficient and Nusselt number in rolling motion could predict the flow and heat transfer in pipes in rolling motion correctly. The average discrepancy between theoretical correlations and experimental data is about 15%. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.
