摘要：
Thevelocity and temperature profile of laminar flow in tubes in rolling motion was developed by analyzing the laminar flow theoretically. The effect of rolling motion on laminar temperature was investigated. In rolling motion, the fluid temperature oscillates periodically. Its oscillation period is half of the rolling period. The temperature gradient next to the wall is very big. The additional force due to rolling motion can alter the velocity profile and enhance heat transfer by increasing the temperature gradient.
