A broken section method for analyzing the two-phase flow of polymer melts in a sandwich sheeting die under a pressure gradient, is presented. The method assumes that the laminar flows are isothermal and the incompressive materials are power-law fluids. Two polymer melts having different flow behaviors are extruded from two extruders respectively into a coaxial manifold and simultaneously, flow into slits perpendicular to the manifold axis, and then contact with each other in the final slit of the sheeting die for laminating the sandwich sheet. The immiscible interface of these adjacent flows in this final slit is determined by a method of variation. Simultaneous equations in many broken sections are analyzed by computerized successive approximation. Uniformity is defined for both core and skin layers. |
