Thermocapillary convection has a very different history for water than for other liquids. For water, several studies have pointed to the lack of evidence supporting the existence of thermocapillary (or Marangoni) convection. Other studies have given clear evidence of its existence and of the role it plays during steady-state water evaporation. We examine both sets of data and suggest a reason for the difference in the interpretation of the experimental data. For organic liquids, the evidence of thermocapillary convection has been clearly documented, but the issues are the type of flow that it generates during steady-state evaporation. We review the measurements and show that the flow field of the evaporating liquid is strongly affected by the presence of the thermocapillary convection. When the results obtained from both water and organic liquids are compared, they give further insight into the nature of thermocapillary convection.
热毛细对流在水中的历史与在其他液体中的历史截然不同。对于水而言，多项研究指出缺乏支持热毛细（或马兰戈尼）对流存在的证据。而其他研究则给出了其存在的明确证据以及它在稳态水蒸发过程中所起作用的证据。我们审视了这两组数据，并提出了实验数据解释存在差异的一个原因。对于有机液体，热毛细对流的证据已有明确记载，但问题在于它在稳态蒸发过程中产生的流动类型。我们回顾了相关测量结果，并表明蒸发液体的流场受到热毛细对流存在的强烈影响。当比较从水和有机液体中获得的结果时，它们能让我们进一步深入了解热毛细对流的本质。
