Numerical modelling of pollution dispersion in complex terrain

Author(s): T. Bodnar, Ph. Fraunie, K. Kozel & L. Benes

Abstract:
The aim of the presented work is to develop a mathematical model for pre- diction of flow and pollution dispersion in Atmospheric Boundary Layer (ABL).

Three different mathematical models based on the system RA-NS equations and its simplifications are introduced and solved.

Systems are completed by the transport equations for passive impurities and potential temperature.

A simple turbulence closure is used.

Resulting systems of governing equations are solved by explicite finite-volume or semi-implicit finite-difference schemes on structured boundary fitted mesh.

Results of simple test computations are presented and discuss...
