Characteristic Angles in the Wetting of an Angular Region: Surface Shape
نویسندگان
چکیده
The shape of a liquid surface bounded by an acute or obtuse planar angular sector is considered by using classical analysis methods. For acute angular sectors the two principal curvatures are of the order of the (fixed) mean curvature. But for obtuse sectors, the principal curvatures both diverge as the vertex is approached. The powerlaw divergence becomes stronger with increasing opening angle. Possible implications of this contrasting behavior are suggested. PACS: 68.03.Cd — Surface tension and related phenomena

تأثیر نوع ساختار و زبری سطح بر زاویه ترشوندگی یک چدن هیپویوتکتیک با آب
Preliminary results of a research on the effects of microstructure and surface roughness of a hypoeutectic cast iron on its wetting angle are presented in this article. For this purpose, molten cast iron was solidified at different cooling rates to produce two samples of the same composition, i.e. a gray cast iron with A type flake graphite and a white cast iron. Two samples were then prepared ...
متن کاملCharacteristic Angles in the Wetting of a Wedge-Shaped Region
The shape of a liquid surface bounded by an acute or obtuse wedge is considered by using classical analysis methods. For acute wedges the two principal curvatures are of the order of the (fixed) mean curvature. But for obtuse wedges, the principal curvatures both diverge as the vertex is approached. The power-law divergence becomes stronger with increasing opening angle. Possible implications o...
متن کاملWetting Behaviors of Phenol- and Urea-formaldehyde Resins as Compatibilizers
Understanding wetting behavior and surface coverage of resins on a wood surface is important to obtain satisfactory adhesion and optimize adhesive application for wood composite manufacturing. Sessile and micro-droplets of ureaand phenol-formaldehyde (UF and PF) resins were generated on wood surfaces to observe wetting behaviors using three directional image generation system and atomic force m...
متن کاملDeposit growth in the wetting of an angular region with uniform evaporation.
Solvent loss due to evaporation in a drying drop can drive capillary flows and solute migration. The flow is controlled by the evaporation profile and the geometry of the drop. We predict the flow and solute migration near a sharp corner of the perimeter under the conditions of uniform evaporation. This extends the study of Popov and Witten [Phys. Rev. E 68, 036306 (2003)], which considered a s...
متن کاملStudy of Reactive Wetting of Sn–0.7Cu and Sn–0.3Ag–0.7Cu Lead Free Solders during Solidification on Nickel Coated Al Substrates
Microstructure, wetting behavior and interfacial reactions between Sn–0.7Cu and Sn–0.3Ag–0.7Cu (SAC0307) solders solidified on Ni coated Al substrates were compared and investigated. Microstructure of Sn–0.7Cu alloy exhibited a eutectic matrix composed of primary β-Sn dendrites with a fine dispersion of Cu6Sn5 intermetallics whereas microstructure of SAC0307 alloy exhibited coarser Cu6Sn5 and f...
