Asymptotic solutions to the Smoluchowski's coagulation equation with singular gamma distributions as initial size spectra
(2007) In Journal of Colloid and Interface Science 309(2). p.440444 Abstract
 Smoluchowski's coagulation equation is studied for the kernel K (u, v) = E(u(alpha)v(beta) + u(beta) v(alpha)) with real, nonnegative alpha, beta and E, using gamma distributions with a singularity at zero volume as initial size spectra. As the distribution parameter of the gamma distribution, p, approaches its lower limit (p > 0) the distribution becomes similar to pv(p1) 1 for small v. Asymptotic solutions to the coagulation equation are derived for the two cases p > 0 and v > 0. The constant kernel (alpha = beta = 0) is shown to be unique among the studied kernels in the sense that the p > 0 asymptote and the v 0 asymptote differ.
