Abstract
In 1805, Young described the so-called Young’s equation for a liquid drop resting on a planar surface, which since has been successfully applied for different designs and extended to cover various physical situations. In this paper, we used the method developed by Lubarda to derive a Young’s equation for a liquid drop resting on an axisymmetric concave surface, which is considered to account for an extended form of nonplanar surfaces. As a result, a new form of Young’s equation is derived, which can be reduced into the Young’s equation for either a planar boundary or a vertical tube and accordingly can be considered as an extended form of Young’s equation for surfaces of various forms.
