在制药工业中进行的许多操作都是在配备有后退叶片叶轮（RBI）和不同类型的单挡板之一的搪玻璃容器中进行的。关于RBI耗散的功率和这种系统的流体动力学的信息很少。在这里，湍流的功率数，Po的，为RBI在一个缩小的容器配备了一个不同类型的单一的挡板在制药工业中使用（海狸尾巴，D型，H型，指型，鳍型挡板）的实验确定的挡板的不同位置，并计算得到，连同速度分布。涡的形成，发生与海狸尾挡板，也量化实验和计算。实验Po值与计算预测非常吻合。此外，一个简单的幂律相关性建立之间的PO和无量纲的垂直横截面积的挡板，从而在一个方程与实验数据拟合良好。
Many operations conducted in the pharmaceutical industry take place in glass-lined vessels provided with a Retreat-Blade Impeller (RBI) and one of different types of single baffles. Little information is available on the power dissipated by the RBI and on the hydrodynamic of such systems. Here, the turbulent Power Numbers, Po’s, for an RBI in a scaled-down vessel equipped with one of the different types of single baffles used in the pharmaceutical industry (beavertail, D-type, H-type, finger-type, fin-type baffles) were experimentally determined for different positions of the baffles and computationally obtained, together with the velocity distribution. Vortex formation, occurring with the beavertail baffle, was also quantified experimentally and computationally. The experimental Po values were in close agreement with the computational predictions. Additionally, a simple power-law correlation was established between Po and the dimensionless vertical cross-sectional area of the baffles, resulting in an equation with a good fit with the experimental data.
