Droplets impact on textured surfaces: Mesoscopic simulation of spreading dynamics
چکیده انگلیسی

- We model the solid-fluid interaction with three linear weight functions which can generate a large range of wettability.
- A simple but efficient method is introduced to measure the contact angle.
- Our MDPD system can capture and show the contact angle hysteresis in either gentle impact or high speed impact and the drop deformation on different textured surfaces realistically.
- Our simulation shows the both rebound and adhesion of drops depend on materials property, surface morphology and impact velocity largely.
- Our simulation shows high impact velocity can make drop spread excessively and be pinned on surfaces and this is related closely to the apparent receding contact angle.
