| description | Droplet disintegration behavior on slender cylindrical objects is critical in various applications. This work investigates droplet impact dynamics on hydrophilic cylindrical glass fibers by using a high-speed imaging method. The influences of liquid viscosity, surface roughness, and surface tension are examined, revealing two distinct disintegration patterns: T-shaped and wing-like. T-shaped disintegration is a never-reported phenomenon that only occurs under very low viscosities, whereas wing-like disintegration tends to appear under higher viscosities and challenges the previous understanding that high viscosity promotes liquid wrapping on fibers. A regime map is constructed by varying impact velocity and liquid viscosity, and an empirical threshold model is proposed. Besides, surface roughness can also enhance wing-like disintegration, equivalent to the effect of directly increasing liquid viscosity. Additionally, a second regime map is developed by varying impact velocity and surface tension, and a theoretical threshold model based on the Plateau–Rayleigh theory is established. This work extends the understanding of droplets impacting fibers, illustrating that droplet disintegration is not necessarily favored by low-viscosity droplets or by surface hydrophobicity. |
