实验研究了氨基酸离子液体（AAIL）水溶液在竖直均匀加热平面上的降膜流动特性。红外图像和温度分布已被确定，并用于分析流体流动。研究表明，Marangoni效应广泛存在，并对降膜流动区域有重要影响。当AAIL的质量分数为30%时，还观察到了一种新的流型。流型也被证明是受壁面液体温差，流量和溶质浓度。AAIL降膜的实验结果为离子液体的进一步工业应用提供了参考。
The flow characteristics of falling film of amino acid ionic liquid (AAIL) aqueous solution on a uniformly heated vertical plane have been experimentally studied. The infrared images and temperature profiles have been determined and used to analyze the fluid flow. It is proven that the Marangoni effect exists widely and has significant influence on the flow region of falling film. A novel flow pattern is additionally observed when the mass fraction of AAIL is 30%. The flow patterns are also shown to be affected by the wall-liquid temperature differential, the flow rate and the concentration of solute. The experimental results of AAIL falling film are expected to be helpful for the further industrial application of ionic liquids.
