Creeping flow of a polymeric liquid passing over a transverse slot with viscous dissipation

摘要

Numerical simulations for the non-isothermal flow of a nylon-6 fluid passing over a transverse slot with heat dis- sipation are considered with a differential-type non-isothermal White-Metzner model describing the non-Newtonian behavior of the melt. The results obtained in the study are computed by using the elastic-viscous split-stress finite element method incorporating the non-consistent streamline-upwind scheme. As a verification of the numerical scheme, the algorithm is first applied to compute the corresponding isothermal flow of the upper-convected Maxwell fluid, a special case of the melt, characterized by constant viscosity and relaxation time.
