Abstract

Mathematical model of nonisothermal flow of elastomeric compounds in a flat channel in the conditions of possible premature vulcanization is presented. All important factors to be taken into account in the development of the rheological model (RM) have been noted. Ellis model is used as RM. Assumptions were made taking into account low values of the Reynolds number and a high Peclet number. Thermal boundary conditions of the first kind, the dependence of viscosity on the temperature and the degree of conversion, as well as the energy dissipation are taken into account. From the momentum equation using this RM, the velocity profile (VP) is obtained as expressed in an explicit form. The solution of the energy equation was analyzed numerically by the finite difference method using iterative scheme. Results of calculations have been presented. The role of near-wall layers has been considered. A significant effect of possible premature vulcanization on VP transformation along the channel has been shown.
