Statistical description of coagulation in finite spatially inhomogenous systems (Part 2)

Abstract

An analysis of statistical properties of spatially heterogeneous systems has been carried out for constant coagulation nucleus and droplet diffusion coefficient. A universal connection is found for particle size distribution function and particle mean number. It is shown that all possible statistics controlling the particle number in a system can be subdivided into narrow, Poisson-like and broad distributions. In this case initial subdivision of a statistics into a class of narrow distributions remains with time, as for broad statistics—it goes to the class of a narrow one with time. It is shown that the existence of spatial microfluctuations leads to an increase of spectrum large-droplet fraction. This effect is a fluctuation source of large droplets playing a considerable role in understanding the precipitation formation process.
