Název v původním jazyce

Numerical Tests of Flows in Coal Field

Popis výsledku v původním jazyce

The paper deals with a mathematical and numerical investigation of the influence of a forest stand on the atmospheric boundary layer flow over the complex topography given by a surface coal field located in the North Bohemia. The homogeneous forest standis simulated through the additional source term on the right hand side of the momentum equations which depends on the local velocity magnitude, the characteristic area of the obstacle and on the drag coefficient. The forest free area is supposed to be covered by a low vegetation and its influence is included to a surface roughness parameter. Two mathematical flow models have been applied and the results compared: 1) full RANS equations considered in the conservative form and 2) modification of RANS equations, based on the Boussinesq approximation, written in the non-conservative form. A simple algebraic turbulence closure is performed and a stationary boundary conditions are supposed.
