3D model of the interaction between air stream and forested area

Differential equations in partial derivatives of motion, continuity and diffusion with corresponding border and initial conditions are used to describe a process of pollutants mechanical accumulation by forested area and following take-away from it. Equation system is closed using semi-empirical turbulence model. The problem is formulated in 3D formulation, forested area is simulated as semipermeable media with distributed resistance force. For numerical solution the geometrical decomposition of differential equations in partial derivatives into sequence of uniaxial problems method is applied.
