Abstract

Solution of the 3D turbulent diffusion equation, based on the alternating direction method, is proposed. The advantage of this scheme is its physical validity and high stability. The numerical algorithm, developed, allows including the computing unit of air pollution dispersion in the 3D unsteady boundary layer of the atmosphere.
