Energy transfer to molten flowing polymers has been studied. A comprehensive literature survey of heat transfer in non-Newtonian systems with particular emphasis to polymer melts has been described. Forrest and Wilkinson's theoretical treatment for evaluation of laminar flow heat transfer to non-Newtonian, non-isothermal, viscous fluids has been extended and modified by inclusion of thermal expansion effect in the energy equation. Resultant differential equations of change have been solved simultaneously for the following boundary conditions: (a) constant wall temperature; (b) constant heat flux; (c) arbitrary axial variation of the wall temperature.
