棒销式搅拌磨机流场的数值模拟分析

采用FLUENT对棒销式搅拌磨机磨腔内的流场进行数值模拟,通过分析流场速度、湍流强度和剪切率参数,研究了磨腔内流场的运动规律。结果表明,随着搅拌器转速的增加,流场内的能量传递充分性降低,能量利用下降。通过对其数值模拟的研究,更加直观的了解搅拌磨矿机磨矿作业的工作原理,为机械参数的优化设计提供了理论依据。

Numerical simulation and analysis on flow field of pin-stirred mill

The flow field in grinding chamber of pin-stirred mill was numerically simulated by FLUENT, analyzed the parameters such as velocity, turbulence intensity and shear rate, the motion law of flow field in grinding chamber was studied. With the increase of agitator speed, the energy transfer in the flow field was lower and the energy utilization was not favorable. Through the numerical simulation research, more intuitive understudied of the mill grinding operation principle, and provided the theoretical basis for the optimization design of mechanical parameters.
