Abstract

We investigate the effect of a finite droplet volume fraction on the Ostwald ripening on the basis of the statistical theory recently developed by us. The theory takes into account both the competitive growth and soft-collision effect of droplets arising from statistical correlations among them. The Lifshitz-Slyozov-Wagner scaling law is found to hold. The scaled droplet size distribution function and the average droplet size are determined self-consistently, up to order Q 1 2 , Q being the volume fraction, by numerically solving the kinetic equation of the theory for long times. The results are in excellent agreement with those of the computer by Voorhees and Glicksman within the data scatter, which is not the case if soft-collision processes are omitted as in all the previous theories.
