Abstract Because of the effects of the nanostructure, phase change behaviors on flat and nanostructured surfaces display distinct features. In this work, the molecular dynamics simulation method is employed to investigate the onset temperature of explosive boiling (Ts) with various film thicknesses, pillar heights, and wettability. The simulation results show that Ts decreases with the film thickness on both wettability flat surfaces. However, the decreasing rates have the significant distinctions, where the difference between two surfaces of Ts with the identical film thickness decreases. In addition, the simulation results demonstrate that all the values of Ts on nanostructured surfaces are lower than those on flat surfaces with the same film thickness. With the increase of the film thickness, Ts presents a decreasing trend on both wettability and nanostructured surfaces, especially with the liquid film with the thickness over 6 nm, where a completely opposite conclusion compared to the flat surface is represented.

平面和纳米结构表面上液态氩薄膜的爆炸沸腾

摘要 由于纳米结构的影响，平面和纳米结构表面上的相变行为表现出不同的特征。在这项工作中，采用分子动力学模拟方法研究了具有不同膜厚、柱高度和润湿性的爆炸沸腾开始温度 (Ts)。模拟结果表明，在两个润湿性平面上，Ts 都随着薄膜厚度的增加而减小。然而，下降率具有显着差异，其中具有相同膜厚的Ts的两个表面之间的差异减小。此外，模拟结果表明，纳米结构表面上的所有 Ts 值都低于具有相同膜厚的平坦表面上的 Ts 值。随着膜厚的增加，
