Abstract
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.
