Investigation of Hollow and Dense Droplet Impact on Solid …
WebThe impact of liquid drops on a rigid surface is central in cleaning, cooling, and coating processes in both nature and industrial applications. However, it is not clear how details of pores, roughness, and texture on the solid surface influence the initial stages of the impact dynamics. Here, we experimentally study drops impacting at low velocities onto surfaces … WebJul 21, 2024 · The solid-surface roughnesses of bamboo leaves covered the entire lifecycle. ...

WebMay 1, 2001 · When the molecular interactions between the water and the surface are repulsive, water droplets landing on these so-called hydrophobic solids try to minimize their contact with the surface. Thus, after being forced into a pancake shape, the drops retract as they try to re-establish a spherical form to minimize their exposure to the solid. WebJan 12, 2024 · 2.1 Computational domain. Figure 1 illustrates the 2D axisymmetric calculation domain of the hollow oil droplet impact on the heated wall. Figure 1 depicts the vertical impact of the hollow droplet with an initial velocity \(U_{\mathrm {0}}\) on the horizontal wall. The hollow droplet at the initial time only reaches the wall, and the bubble, … WebThe conditions are expressed as follows: a glycerin hollow droplet with an initial diameter Dp = 5.25 mm and dimensionless shell thickness δ p ∗ = 0.082 at 5.94 m s −1 velocity … blocking email addresses yahoo
