Abstract

Abstract: A new π-type static mixing element developed by the authors was tested for its fluid dynamics and heat transfer performance. The test results were compared with those of the Kenics element. The π-type element was shown to be effective in enhancing heat transfer.

摘要： <正>静态混合器是七十年代发展起来的一种管式静止混合设备,广泛应用于混合、萃取、乳化、吸收和传热等化工单元操作,尤其适用于气体和中、高粘度液体介质的传热,强化效果十分显著.所用元件的类型达30多种.作者在对现有静念混合元件进行分析的基础上,提出了一种结构简单的π型元件,这种元件可简单地依靠扭曲(或冲压)成型.图1是π型元件的结构示意图,用扭角大小来表示元件成型后的扭曲程度.
