| 摘 要： | 采用三维建模软件Pro／E建立三维实体模型，利用FLUENT6．0大型计算流体力学软件，采用非结构化四面体网格，利用动坐标系技术，采用κ-ε湍流模型和SIMPLE算法，对新型流线型两叶片XCK搅拌器进行了流场模拟，分析了全罐的速度矢量图，并对该新型搅拌叶片处于不同安装高度的搅拌流场进行了对比，发现轴流式叶轮比径流式叶轮的搅拌效果要好．计算结果表明，该新型搅拌器流场为轴对称，属于轴流式搅拌器；该新型搅拌叶片安装在搅拌罐中部时，轴向流最突出，搅拌循环最明显．

| Abstract: | The inner flow of a new-type streamline shape XCK mixer with two blades was simulated by using unstructured-tetrahedron grid and MRF technology in Fluent 6.0. The flow characters of the mixer at different heights installation were compared. The mixing effects by axial-flow blade and runoff-flow blade were compared, and the former showed better mixing effect than the latter. Results show that the mixer＇s flow is axial-symmetrical and the axial-flow is the most prominent as the mixing blades are fixed in the center of the mixing tank. |
