Abstract
High concentration of atmospheric dust is a well known risk factor to human health. Vegetative barriers are one of the most popular ways how to substantially reduce the high pollution concentration. Correct modelling of air flow inside the Atmospheric Boundary Layer (ABL) is essential to accurately predict concentration of the passive scalar (dust). The question whether the CFD toolbox OpenFOAM is capable of modelling of this type of problems is tested in the contribution. The results obtained from OpenFOAM were compared simultaneously with the experimental data and the CFD results of the program Atifes, developed at CTU for ABL simulations. It is shown that the recommended setting of OpenFOAM’s atmospheric library has several limitations. Special attention is paid to the different wall functions used in both solvers and the differences are discussed.
