Splet11. jun. 2008 · Abstract When a liquid drop contacts a wettable surface, the liquid spreads over the solid to minimize the total surface energy. The first moments of spreading tend to be rapid. For example, a millimeter-sized water droplet will wet an area having the same diameter as the drop within a millisecond.

Splet01. okt. 2024 · Observations of spontaneous drop spreading reveal that spreading occurs through three distinct regimes: an initial spreading regime, a short transition regime and a viscous regime. In this study, we show that the spreading radius in the inertia-dominated early time dynamics scales as r ~ t α, where the exponent varies moderately with … SpletShort time dynamics of viscous drop spreading A.

SpletFIG. 3. Evolution of the spreading radius r as a function of time. The radius is simultaneously determined from the bottom view (blue diamonds) and from the side view (red triangles). Both measurements agree at times larger than 10−3 s, but there is a large discrepancy at shorter times. The side view data present a horizontal plateau whereas … Splet23. jan. 2024 · For highly viscous drops the viscous stresses within the liquid also affect the interplay between the drop and the gas. Here the drop also forms a central dimple, but its outer edge is surrounded by an extended thin air film, without contacting the solid.

SpletWe show that short time spreading does not exhibit a pure power-law growth. Instead, we find a spreading velocity that decreases logarithmically in time, with a dynamics identical to that of coalescing viscous drops. Remarkably, the contact line dissipation and wetting effects turn out to be unimportant during the initial stages of drop spreading.
