Improved physical and mathematical models of polymer melting in screw extruder channels are proposed. The basic distinction of these models is that three phases, namely, a solid porous plug, a mixture of melt, solid granule residuals, and gas, and a fully molten material, interact in the melting zone. Distributions of speed and temperature of the material in the screw channels are determined with due regard for the influence of barodiffusion, convection, and collapse of the plug. Evolution of plug collapse and melting processes is studied.
