Showing papers on "Population balance equation published in 1978"

TL;DR: In this paper, the method of collocation using two finite element techniques is applied to the solution of the general population balance equation for particulate systems, and numerical solutions by both techniques are obtained in six cases for which analytical or asymptotic solutions are available.

TL;DR: In this paper, a population balance equation is derived for dropwise condensation which considers both the drop growth due to direct condensation and the coalescence between drops, which is solved numerically to obtain drop size distributions for various conditions.

TL;DR: In this article, the authors studied the dynamic behavior of aerosol size distributions by selecting simplified, but physically realistic, mechanisms for coagulation, condensation, nucleation, and removal.

TL;DR: In this paper, the effects of Brownian coagulation, turbulent deposition and turbulent co-agulation of aerosol particles were studied experimentally by observing the time-dependent changes in particle number concentration in various turbulent pipe flows, using the ultramicroscopic technique of size analysis.
