The flowing and heat transfer characteristics of turbulent flow in tubes in rolling motion are investigated theoretically. The flowing and heat transfer models of turbulent flow in rolling motion are established. The correlations of frictional resistance coefficient and Nusselt number are derived. The results are also validated with experiments. The effects of several parameters on Nusselt number are investigated. The oscillating amplitude of Nusselt number is in direct ratio with Prandtl number and rolling frequency approximately. The more the flowing velocity is, the less the effect of rolling motion on the flow is. The variation of initial phase difference between Nusselt number and rolling motion with rolling frequency is very limited.Copyright

The flowing characteristics of turbulent flow in rectangular channels in rolling and heaving motions are investigated theoretically with FLUENT code. The flowing model of turbulent flow in rectangular channels in rolling and heaving motion is established. The effects of several turbulent models and parameters on the flow are analyzed. In rolling motion, the velocity profile in channel center is more averaged. The mixing coefficient can be strengthened significantly in rolling motion. The effect of heaving motion on turbulent flow is more limited than that of rolling motion. The turbulent kinetic energy and fluctuating velocity in rolling motion are greater than that in heaving motion and steady state. The effect of rolling motion on the turbulent flow can be depressed by the tube wall.Copyright
