S. Simons, ON THE STEADY-STATE EQUATION FOR PARTICLES UNDERGOING SIMULTANEOUS BROWNIAN DIFFUSION AND COAGULATION, Journal of physics. A, mathematical and general, 29(2), 1996, pp. 303-307
An earlier calculation of the solution of the time-independent equatio
n for the diffusion of coagulating particles is modified to take into
account the correct dependence of the Brownian diffusion coefficient o
n particle size. Explicit analytic results are obtained for the spatia
l dependence of the particle number density N and the volume fraction
of particulate matter phi.
