| Description
| - Mezní vrstvou atmosféry rozumíme její nejnižší vrstvu při povrchu země. Její výška se pohybuje v závislosti na tvaru a typu terénu od desítek metrů do jednoho kilometru i více. Je to vrstva nejvíce ovlivněná aktivitou člověka, včetně negativních jevů jako je znečištění ovzduší. Vytváříme matematický model popsaný Navier-Stokesovými rovnicemi pro proudění a difuzně-konvekční rovnicí popisující šíření znečištění a řešíme jej metodou konečných prvků. Používáme jednoduchý algebraický model turbulence zavedením turbulentní viskozity a ukazujeme použití vhodné okrajové podmínky na terénu. (cs)
- The atmospheric boundary layer is the lowest layer over the surface, where the effects of the viscous force are significant. The air flow is determined by the ballance between viscous and Coriolis force, pressure and Archimedean force. Its thickness extends from tens of meters to more then one kilometer in dependence on terrain shape and type of the surface. It is the part of the atmosphere where we live, and thus the one most heavily affected by human activity. Air pollution is one of the serious problems in almost all countries, especially those with high population density and large industrial centers. We create a mathematical model based on stationary Navier-Stokes equations for air flow and diffusion-convection equation describing pollution transport, and solve the model using finite element methods (FEMs). We present a simple algebraic turbulence model with turbulent viscosity and show the treatment of boundary condition on the bottom border of the domain.
