COUETTE FLOW OF A JEFFREY FLUID IN A ROTATING CHANNEL

The steady flow of a Jeffrey fluid between two infinite parallel plates separated by a distance h is investigated. The upper plate moves with constant velocity U in x ? direction, where the x ? axis is taken on the lower stationary plate. The channel is rotating with an angular velocity ? about y ? axis. Th e velocity field and the temperature distrubation are obtained. When 1 ? ? , the results obtained reduce to corresponding ones of Jana and Datta [21] for Couette flow of a Newtonian fluid in a rotating system. The effects of various phy sical parameters on the velocity and temperature are discussed in detail. It is observed that the velocity and the temperature increase with an increase in Jeffrey parameter 1 ? .
