A new technique for the solution of diffusion equation systems for reacting pollutants

In this paper it is shown how equation systems describing the vertical diffusion of reacting pollutants can be efficiently solved without employing operator splitting. The proposed technique is based on a selfadaptive predictor-corrector method the idea being to replace each inversion of a (K·J)²-matrix by 2K-1 inversions of J²-matrices. As an application, simulation results for the transport and the chemical transformation of motorcar emissions are presented.
