【摘要】 根据基本假设,建立了阿基米德螺线式混炼盘中熔体流动数学模型和混炼过程的计算模型,并进行了数值计算,分析了混炼盘的螺槽深度、螺槽宽度以及转速对螺槽中熔体的停留时间、剪切速率和剪切应力的影响。更多还原

【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.更多还原
