WebThis cellular, equivalent-capillary concep-tualization of pores is especially relevant to hydraulic behavior, as has been recognized for more than 70 years. The initial application was to Haines jumps, illustrated in Figure 3, still considered the basic phenomena of capillary hysteresis. The pore openings, which control WebIt first induces Au nanoparticles (NPs) floating on the water surface. Then, it compresses the sparse Au NPs into a densely close-packed array by creating an effective capillary gradient along the water surface. This study indicates that the effects of the capillary gradient depend on water solubility and vapor pressure of a compressing solvent.

Capillary dynamics of coupled spherical-cap droplets

WebThe capillary, a straight cylindrical tube, is filled with a Newtonian viscous fluid. A spherical particle is arbitrarily positioned in the capillary either co-centrically or eccentrically and is free to translate and rotate. Flow in the capillary is first assumed to be caused solely by the movement of the sphere under the gravity. Web21. máj 2007 · Centre-of-mass motions of two coupled spherical-cap droplets are considered. A model with surface tension and inertia that accounts for finite-amplitude deformations is derived in closed form. Total droplet volume λ and half-length L of the tube that connects the droplets are the control parameters. The model dynamics reside in the … how to add high priority to gmail email

Web20. máj 2013 · Inducing anisotropic interactions between isotropic spherical particles requires the imposition of a directional external field or template; this has been achieved through application of electric or magnetic fields (9) or by immersing the particles in anisotropic fluids (10). Capillary pressure in a tube [ edit] Spherical meniscus with wetting angle less than 90° In a sufficiently narrow (i.e., low Bond number) tube of circular cross-section (radius a ), the interface between two fluids forms a meniscus that is a portion of the surface of a sphere with radius R.
