摘要：

Theoretical analysis on the fluid flow in a vertical channel under rolling motion is performed to establish the mathematical model. The velocity distribution in the channel is derived from the model. The fluid flow near the channel wall is essentially investigated. The analysis shows that, the channel flow under rolling motion is different from the conventional unsteady flow. The boundary layer near the channel wall is destroyed and the cause is figured out based on the flow analysis. Furthermore, the mechanism of the effect of rolling motion on heat transfer is propounded. That is the rolling motion enhances the disturbance in the fluid flow near the heating channel wall.
