Short-time dynamics of partial wetting

Splet20. sep. 2024 · The short time dynamics in capillary regimes are mostly governed by the competition between inertial or Rayleigh time scale ( τ i = ρ r 3 / γ) and viscous time scale ( τ v = ρ r 2 / μ ). In Fig. 2 (d), dimensionless drop base radius is plotted for each experimental case against dimensionless time (non-dimensionalized by the inertial time scale). SpletPerson as author : Pontier, L.

Splet27. sep. 2012 · We 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... SpletThe spreading dynamics of small polydimethylsiloxane (PDMS) drops was studied on substrates with varying surface energies. For experimental parameters near the wetting transition, we observed small PDMS drops of different drop volumes as a function of time using interference video microscopy.

SpletThe contact angle is known as a static contact angle when the contact line is stationary with respect to the solid substrate. Young's equation in Eq. () is therefore a description of the static contact angle.On the other hand, if the contact line is moving relative to the solid, the contact angle, whether it is advancing or receding, is known as a dynamic contact … Splet11. jun. 2008 · This website requires cookies, and the limited processing of your personal data in order to function.

Splet11. jan. 2024 · We present a solvable model inspired by dimensional analysis for the time-dependent spreading of droplets that partially wet a substrate, where the spreading eventually stops and the contact angle reaches a nonzero equilibrium value. We separately consider small droplets driven by capillarity and large droplets driven by gravity. Splet19. apr. 2011 · We find a universal law of aggregate spreading at short times, which we interpret through an analogy with the spreading of viscoelastic droplets. At long times, we observe either partial wetting or complete wetting, with a precursor film of cells spreading around the aggregate with two possible states.
