Surface tension contact angle

Bubble size at departure. At departure from a heated surface, the bubble size may theoretically be obtained from a dynamic force balance on the bubble. This should include allowance for surface forces, buoyancy, liquid inertia due to bubble growth, viscous forces, and forces due to the liquid convection around the bubble. For a horizontally heated surface, the maximum static bubble size can be determined analytically as a function of contact angle, surface tension, and... [Pg.67]

Provides measuring techniques of contact angle, surface tension, interfacial tension, and bubble pressure. Suitable methods for both static and dynamic inteifacial tension of liquids include du Nous ring, Wilhelmy plate, spinning drop, pendant drop, bubble pressure, and drop volume techniques. Methods for solids include sessile drop, dynamic Wilhelmy, single fiber, and powder contact angle techniques. [Pg.646]

The extent of adhesion at the polymer/flller interface may be related to various parameters of adsorption and vetting. Factors related to the adsorption of the polymer onto the filler are types of interfacial forces (secondary, primary bonds), molecular orientation/conformation at the interface, and polymer mobility. Contact angle, surface tension, and substrate critical surface tension are among factors related to wetting. [Pg.20]
