有机物水溶液解吸的界面湍动现象的观察与分析
Interfacial turbulence in desorbing surface of tension-lowering solutes from water
摘要
Abstract
The schlieren system was used to capture the onset of transition to turbulence and the interfacial turbulence in desorbing surface of tension-lowering solutes from aqueous solution. Convective structure in ethanol-water solution, isopropanol-water solution and acetone-water solution was alike. When the mass transfer process started, a rapidly growing turbulent region was observed on the surface. Several small round cells appeared on the edge of the expanding turbulent region. These small cells gradually developed into polygon structures as reported by many investigators. After the short instability process, the structures changed into ring-like shapes. In ethyl acetate-water solution, the structures remained clustered shape, and turbulence intensity was stronger. Structural features and turbulence intensity of interfacial convection depended on experimental operating conditions and physical properties of the system.关键词
