Rates of mass and heat transfer at the wall of a square agitated vessel fitted with semicylindrical turbulence promoters were measured using the electrochemical limiting diffusion current technique. Variables studied were promoter diameter, spacing between successive promoters, promoter orientation, impeller speed, and impeller geometry. The data were correlated by empirical dimensionless correlations. The promoters increased both the wall mass transfer coefficients and the volumetric mass transfer coefficients by factors ranging from 1.1 to 1.59 and 1.25 to 2.09, respectively depending on the operating conditions. Vertical turbulence promoters enhanced the rate of mass transfer by 3–29% more than the horizontal promoters. Confirming their economic worth, the turbulence promoters enhanced the mechanical energy utilization of the reactor up to 96%. Power consumption measurements revealed that the ${45}^{°}$ impeller was more energy-efficient than the ${90}^{°}$ impeller up to 54%. Besides the novelty of using turbulence promoters in agitated vessels rather than their common use in flow ducts, the present study used chemically active promoters as a catalyst support in conducting diffusion-controlled catalytic reactions at the wall. The novelty of using chemically active promoters qualified the present promoters to outperform the chemically inert promoters in enhancing the mass and heat transfer rates.

使用电化学极限扩散电流技术测量装有半圆柱湍流促进剂的方形搅拌容器壁上的质量和热传递率。研究的变量是促进剂直径，连续促进剂之间的间距，促进剂方向，叶轮速度和叶轮几何形状。数据通过经验的无量纲相关性进行关联。促进剂根据操作条件分别将壁传质系数和体积传质系数提高了1.1到1.59和1.25到2.09。垂直湍流促进剂比水平促进剂的传质速率提高了3–29％。湍流促进剂证实了其经济价值，使反应堆的机械能利用率提高了96％。${45}^{°}$ 叶轮比 ${90}^{°}$叶轮可达54％。除了在搅拌容器中使用湍流促进剂的新颖性，而不是在流道中普遍使用湍流促进剂之外，本研究还使用化学活性促进剂作为在壁上进行扩散控制的催化反应的催化剂载体。使用化学活性启动子的新颖性使本发明的启动子在提高质量和传热速率方面优于化学惰性的启动子。
