摘要： 文中对八种规格的Kenies型静态混合器进行了立式装置内的空气阻力和传热对比试验,得到了Re=2300—20000范围内的f～Re和Nu～Re关联式;分析了机理;评价了性能;认为适当增加它的标准型元件的扭率和扭角以及使元件之间有一定的间距,可显著降低流动阻力损失,而仍能基本保持标准到的较高的强化传热效果.

Abstract: Eight different Kenics static mixers were investigated with the aim to identify the structural parameters for augmenting heat transfer through reduced flow resisitance. By changing the twist ratio and the twist angle of standard elements, as well as the distance between the elements, such a goal might he attained. Comparative tests with air in vertical Kenics devices weremade in the region of Reynold numbers from 2300 to 20000 to establish f-Re and Nu-Re correlations. Results obtained indicated that heat transfer could be augmented through reduced flow resistance, by appropriately increasing the twist ratio and twist angle of a standard Kenics static mixer However ample distance between the elements was also necessary lor attaining the better in heat transfer performences.
