Simulation of multicomponent aerosol dynamics

A technique for numerical solution of the multicomponent aerosol general dynamic equation is developed and tested. The method is intended to obtain directly the multivariable size-composition distribution without any a priori assumptions about the nature of the distribution. In selecting the numerical method particular attention is paid to simulating simultaneous coagulation and condensation processes, although if condensation is the dominant process a scheme more suitable for pure condensation can be chosen. Numerical solutions are compared with analytical solutions for model problems of pure condensation, pure coagulation, and simultaneous condensation and coagulation.
