Asymptotic Theory of Droplet Spreading After Collision With a Solid Surface

Abstract

The asymptotic theory of droplet spreading at collision with rigid surface in the limit of small number epsilon = h/R much less than 1 is developed. Here h, R is the current height and radius of droplet consequently. The developed model describes the rim formation on the front of spreading droplet and oscillation of the droplet due to the dynamics edge angle. The offered theory has allowed calculating the frequency of droplet oscillation and the maximal radius of the splat. PU - SPRINGER-VERLAG WIEN PI - VIENNA PA - SACHSENPLATZ 4-6, A-1201 VIENNA, AUSTRIA
