aThe technique of determination of the contact angle and surface tension coefficient based on numerical calculation of the geometric characteristics of equilibrium shape of a liquid drop on the horizontal surface is stated. As initial data, the technique suggests using the dimensionless values of drop ...

Contact Angles Cohesive and Adhesive ForcesSurface Tension picture_as_pdf Donate Contact angle is one of the common ways to measure the wettability of a surface or material. Wetting refers to the st…
The contact angle is a measure of the ability of a liquid to wet the surface of a solid body. The shape that a drop takes on a surface depends on the surface tension of the liquid and the nature of the surface. At the boundary between the drop and its gaseous environment, the surface...
The relation between apparent liquid-solid contact angle and surface tension was established for 3 water- repellent materials using both a series of aqueous ethanol solutions and organic liquids. The media included 2 artifically treated sands and one naturally occurring soil. With one exception, there...
