Snigerev] We have investigated the steady creeping nonisothermal fluid flow with free surface for a polymer fluid at the inlet to the molding channel and at its outlet. The fluid motion is described by the mass, momentum, and energy equations complemented by the constitutive Giesekus equation of the fluid state. We have analyzed the distribution pattern of the fluid velocity in the outflowing jet and the pressure, stress, and temperature fields with increasing degree of heating of the molding channel wall. We present the results of calculating the dependence of the swelling coefficient of the polymer fluid on the extension geometry, the rheological model parameters, and the temperature factors.
