    Abstract

    The wall slip flow behavior has been determined for a blend of polypropylene with EP rubber. Experiments and simulations are used to analyze the capillary flow data obtained from the several dies of different diameters. Mooney plots drawn from this data are strongly curved. This is attributed to viscous heating effects and to a more complex slip velocity relation for the blend. The relevant mass, momentum, and energy equations for flow of a power-law fluid through a capillary are solved numerically to incorporate the combined effects of slip and viscous heating, for fitting the capillary flow data.
