WebMay 24, 2024 · In this paper we will describe a series of experiments of droplet spreading on sawtooth-like surface structures with well-defined pitches and angles. A qualitative ‘toy model’ is formulated and... WebJun 24, 2024 · A droplet with r0 = 1 mm first spreads to its maximum extension in a pancake shape at ∼2.3 ms, recedes towards the centre and finally bounces off the surface at ∼16.6 ms.
Dynamic wetting and spreading and the role of topography
WebFindings: While a carbon coating leads to pronounced wettability and spreading along the topographic anisotropy, an inert gold-palladium coating can fully suppress anisotropic … WebWe concentrate on the spreading of a droplet within a recessed stadium-shaped pixel, with applications to the manufacture of POLED displays, and find that the sloping side wall of the pixel can either locally enhance or hinder spreading depending on whether the topography gradient ahead of the contact line is positive or negative, respectively. indianwood country club orion
Controlling droplet spreading with topography
WebThe results show the dominant factors in determining droplet shapes to be surface topography and the self-similarity of the surface structure.
