This paper is aimed to study the relationship between the kneading pressure, power consumption and the planetary motion parameters of a twin-blade planetary mixer for mixing highly viscous fluids by using CFD simulations. An experimental setup is built to measure the kneading pressure with a thin-film pressure sensor. A validated CFD model is used to investigated the kneading mechanism and hydrodynamic behaviors in the mixer. Results indicate that increasing the absolute speed and the speed ratio can significantly increase the maximum kneading pressure, while decreasing the absolute speed or increasing the speed ratio can effectively reduce the power consumption. The correlation of the kneading pressure with planetary motion parameters is obtained by proposing a specific pressure-oriented Reynolds number Re_M-p and a pressure number N_pmax and the correlation of the power consumption with planetary motion parameters is determined by introducing the improved Reynolds number Re_i and power number N_pi.

本文旨在通过CFD仿真研究混合高粘度流体的双叶片行星式混合机的捏合压力，功耗和行星运动参数之间的关系。建立了一个实验装置，用薄膜压力传感器测量捏合压力。经过验证的CFD模型用于研究搅拌机中的捏合机理和流体力学行为。结果表明，增加绝对速度和速度比可以显着提高最大捏合压力，而降低绝对速度或增加速度比可以有效地降低功耗。捏合压力与行星运动参数的相关性是通过提出一个特定的压力导向的雷诺数Re _{M-p来获得的}通过引入改进的雷诺数Re _i和功率数N _pi来确定压力数N _pmax以及功率消耗与行星运动参数的相关性。
