A droplet impacting on a superhydrophobic surface exhibits complete bouncing. The process usually consists of spreading and retracting stages, during which the contacts underlying substrate. Recent research has been devoted to reducing contact time using textured surfaces with different morphologies or flexibilities. Here, we design submillimeter ridges show that droplets bounce off immediately after capillary emptying in petal-like shape at certain Weber number range. absence horizontal...
Reducing the contact time between impacting droplets and superhydrophobic surfaces has attracted much attention in recent years due to importance of controlling heat mass transfer. Previous researchers have proposed several methods, such as lifting before retraction, accelerating retraction process, or splashing droplets. One example includes symmetry-breaking surfaces, which were used accelerate droplet realize fast detachment. However, dependence on impact velocity surface structure scale...
During water droplet impingement onto a rice-leaf-inspired grooved superhydrophobic surface, the unidirectional textures can reduce solid–liquid contact time through modifying impact dynamics. The influence of groove geometry on splashing impacting droplets is still unrevealed. In this study, we experimentally identify bouncing and regimes surfaces varying parameters. Asymmetric spreading retracting are observed surfaces, accompanied by obvious liquid jets generated within grooves. As...
Superhydrophobic surfaces have shown significant potential for the passive anti-icing application due to their unique water repellency. Reducing contact time between impacting droplets and underlying with certain textures, especially applying pancake bouncing mechanism, is expected eliminate droplet icing upon impingement. However, performance of such superhydrophobic against impact supercooled has not yet been examined. Therefore, we fabricated a typical post-array surface (PSHS) flat...
The interaction between ink drops and permeable textiles is complicated but crucial for textile inkjet printing. To address this, a modified model was developed in the current research by employing volume of fluid method. capillary force flow resistance were taken into account momentum equation, enabling simulation both spreading penetration upon impacting textile. evolutions drop morphology, pressure distribution, velocity field investigated. An interesting finding entrapment air bubbles...
The riblet structures of shark skin have a significant biological function for drag reduction, which has been verified. However, it is difficult to fabricate large‐scale bionic surface with high precision and low cost. real micro‐riblets were first measured approximately simplified obtain shark‐skin‐inspired micro‐riblets. Numerical simulations performed explore the drag‐reduction effect surface. According micro‐riblets, nickel mould negative micro‐structures was manufactured by Ultra‐Violet...
Pancake bouncing of water droplets on superhydrophobic surfaces has been extensively studied, because the reduction in solid–liquid contact time shows great potential for self-cleaning, anti-icing, etc. However, behavior a pancake-bouncing droplet ambient air and its subsequent interaction with underlying surface remain unrevealed, which is actually crucial practical applications. In this Letter, we comprehensively investigate overall dynamics post-array by extending range impact velocities....
