摘　　要：采用CFD方法分别对三角形挡板和长方体空心挡板的双层斜直叶桨搅拌槽在水中产生的三维流场进行数值模拟,选取多重参考系法和标准k-ε湍流模型进行模拟,对两者的轴向平面速度场和时均速度分布进行了详细的对比分析,研究结果对搅拌槽的设计和实际应用具有重要的参考价值。The CFD method was adopted to simulate 3D flow field of the stirred tank which boasting of double straight-oblique blades and triangular baffle and rectangular hollow baffle; in the simulation,both multiple reference frame and standard k-ε turbulent model were employed. Comparing and analyzing their axial plane velocity field and averaged velocity distribution can provide the reference for both design and application of the stirred tank.
