The evaporation of thin liquid films, known as microlayers, plays a crucial role in two-phase heat transfer processes, such as those that occur during boiling, in heat exchangers, and in the semiconductor industry. A microlayer forms when a thin liquid film is trapped beneath a (sufficiently fast) growing or moving vapor bubble. The evaporation of the microlayer increases the heat flow and thus contributes to bubble growth. The formation and behavior of microlayers has not yet been sufficiently researched and is therefore poorly understood.
The dewetting process is being investigated within the project using various parameters such as wall overheating, dewetting speed, wall material and properties, and liquid properties. A generic test setup is used to investigate the influence of the above parameters in isolation. Interferometric layer thickness measurement is used to examine the geometry of the microlayer. The local temperature field is recorded with a high-speed infrared camera.
In addition, the measurement results are used to validate numerical models and investigate novel, industry-relevant surface-fluid combinations.
