Receding contact angle
The contact angle is the angle, conventionally measured through the liquid, where a liquid/vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given system of solid, liquid, and vapor at a given temperature and pressure has a unique equilibrium contact angle. However, in practice contact angle hysteresis is observed, ranging from the so-called advancing (maximal) contact angle to the receding (minimal) contact angle. The equilibrium contact is within those values, and can be calculated from them. The equilibrium contact angle reflects the relative strength of the liquid, solid, and vapor molecular interaction.

"Droplet retention on an incline" by S. Ravi Annapragada, Jayathi Y. Murthy et al.
The present study seeks to understand and predict droplet retention on smooth hydrophobic surfaces. The droplet shape and the advancing and Receding contact angles are experimentally measured as a function of droplet size under the action of a gravitational force at different inclination angles. The advancing and Receding contact angles are correlated with static contact angle and Bond number. A Volume of Fluid Continuous Surface Force model with varying contact angles along the triple contact line is developed to predict droplet shape. The model is first verified against a two dimensional analytical solution. It is then used to simulate the shape of a sessile droplet on an incline at various angles of inclination and to determine the critical angle of inclination as a function of droplet size. Good agreement is found between experimental measurements and predictions. The contact line profile and contact area are also predicted. The contact area predictions based on a spherical-cap assumption are compared to the numerical predictions and are found to underpredict the droplet contact area. (C) 2011 Elsevier Ltd.
