A liquid drop that partially wets a solid surface will slide down the plane when it is tilted beyond a critical inclination. Here we report the study of the sliding velocity of such a drop. Experiments for measuring the steady sliding velocity of different liquids of drops are performed. We then con

A description of the entire configuration of liquid drops spreading over a previously wetted solid surface is given in the case of negligible evaporation and small Bond and Weber numbers. Two solutions are developed: an outer one which is valid in the bulk of the drop and an inner solution which app
There have been many experiments that have determined the wetting behavior of liquids on low-energy solid surfaces. These experiments show that, in general, the contact angle, theta, measured through the liquid, increases with increasing liquid-vapor surface tension, sigmalv. Surprisingly, in experi
