Liquid drop movement over an inclined surface using Volume of Fluid model with finite volume method

Abstract

When a liquid drop of given volume is placed on an inclined solid surface then it tends to slide down. This depends on various factors like surface Tension of fluid pair, inclination angle, volume of the liquid, nature of solid surface etc. In an inclined plane, the motion of a liquid drop is due to the effect of gravity force, friction force and viscous effect of liquid drop. If we change the different parameters of the liquid drop then the velocity of the drop will also change accordingly. This work represent the study of movement of liquid drop by varying three parameters namely inclination angle ,surface tension and contact angle for the solid liquid pair using VOF model with finite volume method.in the present work we changes these parameter one at a time by keeping other constant and visualize the effect of this parameter on the velocity of the liquid drop. After that different curve which shows the effect of these parameters are drawn for the given liquid.
