气液传质过程的界面湍动

Interfacial Turbulence in the Process of Gas Liquid Mass Transfer

界面湍动对相际传质具有重要影响。利用显微激光全息干涉技术研究了 CO2 在乙醇 -水溶液中吸收过程的界面湍动情况 ,实验观察了界面湍动强度与溶液浓度的关系 ,结果表明 ,乙醇浓度越高 ,界面湍动强度越大 ,文中对此进行了分析和讨论。

Interfacial turbulence often exerts a significant influence on the interphase mass transfer process.By use of real time micro holographic interference technique,the interfacial turbulence was studied for the absorption process of carbon dioxide bubble by ethanol water binary solution.The influence of the solution concentration on interfacial turbulence intensity was observed experimentally.Experimental results indicate that higher ethanol concentration leads to stronger interfacial turbulence.
