实验研究了存在蒸发界面的水平液层中的热毛细对流对汽/液界面处温度不连续的影响. 对于单纯的热毛细对流从理论和实验已有深入研究,但目前国际对蒸发与热毛细对流的耦合尚缺乏研究. 特别是近期C.A.Ward等人研究发现了蒸发汽液界面处的温度不连续现象. 本文以存在蒸发界面的水平薄液层为研究对象,测量了蒸发界面处的温度分布,研究了普适环境下蒸发和热毛细对流对汽/液界面处温度不连续的影响 |

The stability of thermocapillary convection in a fluid layer has been experimentally and numerically analyzed by many researchers.While the interfacial flow with evaporation,is absent of comprehensive understanding.Recently,C.A.Ward found the temperature discontinuity at an evaporating liquid interface,which couldn't explained by classical theory.In our work,we measured the temperature profiles at the evaporating liquid surface of a horizontal fluid layer,and experimental studied the co-influence of evaporation effect and thermocapillary convection on the temperature discontinuity at the evaporating interface |
