摘要

研究了液滴与铜表面的相互作用。假定底物为超疏水性，润湿角为\( 150^\circ \)。根据下降的体积，Bond和Weber的数值分别约为0.23和1.6。表面及周围空气温度为298 K，液滴温度低5K。采用轴对称坐标系对共轭传热进行了模拟。采用Kistler接触线模型确定液滴在扩散过程中的动态接触角。研究了液滴传播过程中基材上剪切应力和热流密度随时间的变化规律。

Interaction of a Liquid Drop with a Superhydrophobic Surface

The interaction of a liquid drop with a copper surface is studied. The substrate is assumed to be superhydrophobic with a wetting angle of \( 150^\circ \). Based on the volume of the drop, the Bond and Weber numbers are approximately 0.23 and 1.6, respectively. The temperature of the surface and the surrounding air is 298 K, and the temperature of the liquid drop is 5K lower. Simulation of conjugate heat transfer is performed using an axisymmetric coordinate system. The Kistler contact line model is used to determine the dynamic contact angle of a drop during spreading. The change in the shear stress on the substrate and the heat flux induced during the propagation of the drop as a function of time is studied.
