THEORETICAL DAMPED OSCILLATING MODEL OF SEGMENT SPHERICAL DROPLET ON THE SOLID FLAT
Abstract
The purpose of this paper is to present a theoretical damped oscillating mathematics relationship of segment
spherical droplet on solid surface between the radius, volume, kinematic viscosity, density, surface tension
coefficient and contact angle of the droplet. The theoretical equilibrium radii are compared with that of the
numerical results. It has been shown that the theoretical equilibrium radii are larger than that of the
numerical results. In addition, the theoretical model is used to study the effects of different shear stresses on
the amplitude and cycle of droplet spreading radius. It can be found that the amplitude of spreading radius
decreases with the increase of shear stresses. The decay speed of spreading velocity increases with the shear
stress increasing.
