“…The spreading force obtained from the surface tension of the liquid-solid pair at the interface is in agreement with the correlation indicated by Yin [7] and is in contrast to the formulism suggested by Neumann et al [4] . But in this model, we indicated a number of assumptions in agreement with the literature mentioned before.…”

“…So the assumption was in accordance with the reality basically. Moreover, Yin [7] has indicated that when r = 0, the velocity must be zero to satisfy the requirement of circular symmetry, whereas when r≠0, the velocity becomes finite, and the gradient in the r direction unlikely must be zero. But this velocity gradient would only contribute to the vertical force field so that it should not alter the horizontal force balance assumed in eq.…”

“…We find that sv Considering a droplet in the process of spreading onto a smooth and homogeneous solid surface (Figure 1), it keeps the shape of a spherical cap and acquires a circular interfacial contact area with the solid surface. Yin [7] has stated that the driving force of the self-moving wetting is…”

To consider a sessile drop on an ideal solid surface in equilibrium with a vapor phase, the classic Young equation was given. The derivation of the Young equation was based on both the mechanics and the energy knowledge. According to the constant volume of the liquid in the wetting process of the liquid on a smooth and homogeneous solid surface and the low energy law, Young equation was obtained through the mathematic method in this paper. The previous work indicated that the contact angle θ was a function of time, but the coefficient can be obtained only through experiments. It was assumed that the liquid was steady Newtonian flow. Then the relationships between the dynamic contact angles and the wetting time were found in terms of the equilibrium of the spreading force and the restoring force. An immediate theoretical justification for the dependence of contact angles and the time was given. It was assumed that the effect of the gravity on wetting was negligible in the investigation. Under what conditions was the gravity negligible? The criterion of the gravity on the wetting process of the liquid was proposed when contact angles were greater than 90°. If the criterion, I, was much smaller than 1, the effect of the gravity on the wetting process could be ignored. If the criterion, I, was equal to or larger than 1, the effect of the gravity on the wetting process could not be ignored. On mercury-mica systems, the gravity may be considered only when the equilibrium contact radius reached 1.5 mm.kinetics of wetting, equilibrium contact angle, criterion of gravity

“…Wetting and Penetration T. P. Yin 7) indicated by the theoretical formulism that the spreading rate of spherical droplets onto rigid, horizontal substrates correlates with the viscosity and volume of melts and inversely with the surface tension. S. Hara 8) reported that the time required for the contact angle of the slag droplets on alumina substrate to be 60°(namely; the spreading rate) was proportional to the value of h/g (viscosity/surface tension of slag melts).…”
