| Abstract: | According to the conventional assumptions, the authors have established the mathematical model of melt flow for Archimedes spiral mixing disc and the computational model of mixing process. The equations were solved numerically with the aid of computer. The effects of the channel depth, channel width and rotation speed of mixing disc on the re tention time, shear rate and shear stress of melt in channel have been analyzed. |
