The influence of temperature on the dimensions of the vortex flow polymer melt in the region at the inlet of the slotted passage. To solve the problem of mathematical modeling of three-dimensional flow of the polymer melt in a converging plane-parallel channel uses a modified Vinogradov and Pokrovskii rheological model generalized to account for the non-monotonic dependence of the viscosity gradient in uniaxial elongation. Getting discrete analog volume control is carried out by a division into physical processes, and numerical implementation is carried out using techniques of parallel computing based on GPU. The temperature dependence of the rheological properties of the polymer melt is Arrhenius form. The numerical experiment shows that the dependence of the size of the vortex of the melt temperature is non-monotonic.
