摘要:

研究了二氯甲烷(DCM)液膜的零重力蒸发。由此产生的薄膜动力学和稳定的薄膜的标准描述的长波理论的基础上。它的结论是,受长波不稳定性的膜显示的外观的模式的最大增长率在破裂时,无论初始条件或域尺寸的条件。在地球重力下稳定的薄膜在零重力下不稳定。

英文摘要:

Zero gravity evaporation of a Dicholoromethane (DCM) liquid film is explored. The resulting film dynamics are presented and a criterion for stable films is described based on the long wave theory. It is concluded that films subject to long wave instabilities shows the appearance of the mode of maximum growth rate at rupture, irrespective of the initial condition or domain size conditions. Films stable in Earth's gravity are destabilized in zero gravity.
