Abstract A side-entry propeller was designed and introduced in this study. The mixing performance of shear thinning fluids in a cylindrical stirred vessel equipped with this propeller was experimentally investigated via an ultrasonic Doppler anemometer (UDA, experimental results were consistent with theoretical findings. The power number and Reynolds number of this propeller were evaluated by using Chhabra, Metzner and Reed equations. Results showed that the power number versus the Reynolds number curves were highly comparable with Metzner and Reed equations. The velocity jet vectors flow field of 320, 380, and 440 rpm were described in detail. These findings demonstrated that the circulation loops, cavern size, and shape were highly influenced by shear thinning parameters and operating conditions. The average of the velocity profiles from five sample lines in front of the propeller was utilized to analyze the effect of rheological properties and operating conditions on the propeller. The axial, radial and tangential 2D velocity profiles located at one sample line (200 mm) in front of the propeller at the design rotation speed were evaluated.

在装有新型侧入式螺旋桨的圆柱形搅拌容器中混合非牛顿流体

摘要 本研究设计并介绍了一种侧入式螺旋桨。通过超声多普勒风速计（UDA，实验结果与理论结果一致）对装有该螺旋桨的圆柱形搅拌容器中剪切稀化流体的混合性能进行了实验研究。该螺旋桨的功率数和雷诺数通过Chhabra进行评估， Metzner 和 Reed 方程。结果表明，功率数与雷诺数曲线与 Metzner 和 Reed 方程具有高度可比性。详细描述了 320、380 和 440 rpm 的速度射流矢量流场。这些发现表明循环环、洞穴大小和形状受剪切稀化参数和操作条件的影响很大。利用螺旋桨前五个采样线的速度分布的平均值来分析流变特性和运行条件对螺旋桨的影响。在设计转速下，评估了位于螺旋桨前方一条采样线 (200 mm) 处的轴向、径向和切向二维速度分布。
