Droplet motion without energy supply
WebMay 1, 2001 · 1 Making an impact (a) An undeformed drop with diameter D0 hits the surface and spreads out to its maximum diameter, Dmax, within the first 2 ms. The drop subsequently retracts and can either detach from the surface, as happens for pure water (b), or remain bound to the surface, like the polyethylene oxide solution (c).

WebJun 20, 2024 · In order to understand the dynamic behaviors of the charged water droplet in the presence of electric field, the experimental investigation is conducted in this paper. A uniform DC electric field is produced by applying high voltage between two parallel copper plates which are placed horizontally in a silicon oil tank. The variation range of the …
WebThe local droplet motion on surfaces with varied wettabilities is discussed and compared. A unipolar electrostatic field is theoretically simulated. This work can introduce a finger-directed surface charge pattern and local … WebDec 11, 2024 · This generates backspin. The ball is moving fast in a forward direction but also slightly in a backward motion. This is what backspin is. Backspin is most useful for the transition between a long shot to the green. Without backspin, the ball will likely roll on for longer than you would want it to. Using backspin slows the ball down after it ...
WebSep 27, 2024 · Graphene-based electric power generation that converts mechanical energy of flow of ionic droplets over the device surface into electricity has emerged as a promising candidate for blue-energy network. Yet the lack of a microscopic understanding of the underlying mechanism has prevented ability to optimize and control the performance of … WebJan 28, 2024 · In the first part of this research, we reported the experimental study of the drop impact on the superhydrophobic circular groove arrays, which resulted in a directional droplet transport. In the second part, we further explored the influence of the Weber number (We), ridge height (H), and the deviation distance (r) between the impacting point and the …
WebDroplet motion is frequently encountered in our everyday lives but is also relevant to a broad range of applications. In some settings droplets must be avoided, e.g. car windscreens, solar panels, greenhouse covers and heat exchangers need to remain as dry as possible, whereas droplet retention is critical for the efficiency of several
WebJun 19, 2015 · A quantitative description of the dynamics of droplet motion has been a long-standing concern in electrowetting research. Although many static and dynamic models focusing on droplet motion induced by electrowetting-on-dielectric (EWOD) already exist, some dynamic features do not fit these models well, especially the dynamic saturation … culbertson insurance fort myers flWebAbstract: Using extensive molecular dynamics simulation of a coarse-grained model, we demonstrate the possibility of sustained unidirectional motion (durotaxis) of droplets without external energy supply when placed on a polymer brush substrate with stiffness gradient in a certain direction.
