研究了封闭容器中蒸发的二元混合物自身蒸气的不稳定性。在没有重力的情况下，液相和气相的流体动力学也被视为偏转界面。从计算得出的结论是，以低重量醇混合物为例，与单组分系统不同，非稀释二元混合物只有在从蒸气侧加热时才会变得不稳定。这种不稳定性是由相变时触发的溶液马兰戈尼对流引起的。
The instability of an evaporating binary mixture underlying its own vapor in an enclosed container is investigated. The fluid dynamics of both liquid and vapor phases, in the absence of gravity, are taken into account as also a deflecting interface. It is concluded from calculations, exemplified by a low weight alcohol mixture, that unlike single component systems a non-dilute binary mixture can become unstable only when it is heated from the vapor side. This instability is caused by solutal Marangoni convection that is triggered in the presence of phase change.
