Abstract

Abstract

The model of laminar flow in tubes in rolling motion is established.The dimensionless correlation of velocity is derived,and the correlation of frictional resistance coefficient is also obtained.Of all the additional forces,only the tangential force effects on the flow.The effect of centrifugal and Coriolis forces on the flow is counteracted.The correlation of average frictional resistance coefficient is the same with that of no rolling motion.The effect of rolling motion on frictional resistance coefficient of laminar flow diminishes with the increase of Reynolds number.
