FLOW OF A POWER LAW FLUID IN A ROTATING STRAIGHT PIPE - II. HEAT TRANSFER

Abstract

The heat transfer in the flow of a power law ,fluid in a straight pipe of eircular cross-section rotating about a perpendicular axis is studied. The temperature field is evaluated up to the first order of the rotational Coriolis parameter. when the wall of the pipe is maintained at a uniform temperature. It is found that the fluid is uniformly heafed relative to the wall up to n critical value of the parameter a, which involves the Prandtl number and for higher values of a, relatively cooled and heated regions develop. The physiual reasons for such a behaviour are analysed The Nusselt number is not affected by rotation up to the first order of E.
