POSSIBILITIES FOR EXPERIMENTAL MEASUREMENTS
AND MODEL TESTS
Type of test
I. Investigation of local pressures on scale models
(open roofs, roof lining and atypical shapes
structures).

The presented results were achieved under sponsorship
of the Grand Agency VEGA of the Slovak Republic
(grant. reg. No. 01/0544/15 and 01/0265/16) and with
the support of the TU1304 COST action “WINERCOST”.
II. The total wind load.
III. Tests of sectional models - using dynamically
mounted models (bridges, high-rise buildings,
towers, cables and hinges).
IV. Aero-elastic studies - testing using dynamically
similar models of buildings, bridges and
structures (wind-induced response of building
and other structures). Testing of active and
passive damping devices for slender structures of
large spans.
V. Wind in the level of pedestrian - (character of
flow around buildings and structures,
measurement of local wind speed and direction
for environ-mental assessments).
VI. Air Quality - tests for evaluation of the dispersion
of pollutants. Modeling and monitoring dispersal
of pollutants and hazardous substances in the
area of chemical and radioactive devices.
Trajectory of pollution and the resulting air
quality around buildings to urban spaces.
VII. Terrain and topographic studies - tests with small
scale topographic model using a flow
visualization and hot wire anemometer (flow
over complex terrain roughness and estimate the
potential for wind energy of sides, monitoring
soil erosion in deforestation).
The possibilities for using the wind tunnel BLWT STU are
offered not only in area of civil engineering and
architecture, but also in mechanical engineering, the
environment and also forest and land management.
Experimental testing in the wind tunnel allows repeated
measurements at varying wind speed and direction,
which would not be possible in situ with respect to the
stochastic nature of the air flow.
Wind engineering that works with the new software
(CFD), and also new methods of experimental testing of
structures in BLWT tunnel, will provide a new approach
to research at the University of Technology in Bratislava.
We expect closer co
