The VZLU wind tunnel with the simulated atmospheric boundary layer is used for measuring wind-induced load of structures and wind condition simulation in their surroundings. In bridge structures, the floor system dynamic load is measured (bridge´s sector models) along with non-linearity of the whole bridge structure, which leads to generation of aeroelasticity models and their measurement.
There is growing interest of designers to verify calculations using experiments in a wind tunnel with atmospheric boundary layer. Increased attention is also being paid to simulating air flow in built-up areas and determining wind conditions affecting pedestrians (so called pedestrians´ wind comfort). It may be expected in the near future that wind tunnel measurement results will be required by public authorities approving large constructions, as is the case in some foreign countries.
The VZLU wind tunnel with simulated atmospheric boundary layer, which is called BLWT for Boundary Layer Wind Tunnel, is also employed in measuring emission scatter in countryside or towns for environmental studies. In the VZLU wind tunnel with simulated atmospheric boundary layer it is possible to study dust deposits or snow banks (snow-drift formation) near objects or built-up areas. BLWT can also be applied to civil emergency planning to simulate the scatter of dangerous stuff at accidents and to prepare emergency evacuations.
From the model established boundary conditions, wind tunnel experiments, and CFD (Computational Fluid Dynamics) it is possible to simulate smoke flows or smoke propagation in subways or study more complex flow patterns around object models.
