Droplet growth in a dilute vapor

摘要: When the mass flux Γ to a liquid droplet is expanded in terms of parameter α which ratio size mean free path (inverse Knudsen number), one obtains series form Γ=Γ(0) +Γ(1)α + Γ(2)a2lna ···. As shown previous paper, coefficients this are determined by integrals associated with sequences successive collisions among number vapor molecules and droplet. For surrounded its pure vapor, we have calculated coefficient Γ(1) first inverse correction molecular growth rate Γ(0) assuming that can be treated as hard spheres. most nonequilibrium conditions, Γ(1)/Γ(0) turns out positive, rather than negative, heretofore was assumed literature. This result implies reduced Γ/Γ(0) will pass through maximum function number.
