根据齿轮啮合原理，建立了用于高粘度物料混合、输送和松弛的双螺杆捏合机的齿形曲线设计方法和共轭曲面的数学模型。提出了一种新型双螺杆捏合机，给出了双螺杆捏合机转子型线方程和转子设计方法。分析了双螺杆捏合机的工作原理，对其流场的动态特性进行了数值模拟。基于计算流体力学(CFD)理论，对非牛顿流体进行了三维、等温和稳态数值分析，研究了不同速度和中心距条件下的压力分布、速度场、最大剪应力和质量流量等特性。研究结果为新型双螺杆捏合机的性能预测和合理设计提供了理论依据。
The profile curve design method and the mathematical model of conjugate surfaces of twin-screw kneader used for high viscosity material mixing, transportation and malaxating are established according to the principle of gear engagement. A novel twin-screw kneader and the equations of the profile curves of the rotors as well as the rotor design are proposed. The working principles of the twin screw kneader are analyzed and numerical simulations for dynamic characteristics of the flow field are carried out Three-dimensional, isothermal and steady state numerical analysis of a non-Newtonian fluid are presented, based on computational fluid dynamics (CFD) theory, and the characteristics under the conditions of different speeds and center distances are studied, such as pressure distributions, velocity fields, the maximum shear stresses and the mass flow rates. The results provide a theoretical basis for performance predictions and reasonable design for the novel twin-screw kneader.
