Analytical-Numerical Solution of the Multicomponent Aerosol General Dynamic Equation--with Coagulation

A numerical procedure based on an analytical solution is presented for solution of the full muIticomponent aerosol general dynamic equation. The analytical solution for the equation, accounting for growth, removal, and particle sources, is employed in an iterative procedure to account for coagulation. The iterative process is shown to be rapidly convergent, and its performance is validated by comparison with the exact solution for pure coagulation of a single-component aerosol. A simulation is presented of the evolution of a multicomponent coagulating aerosol, where each component grows-evaporates at a different rate.
