In the contribution, we present a laboratory system capable of X-ray computed tomography (XCT) scanning of an periodically moving or oscillating object. The system is an in-house developed XCT setup with electromagnetic voice coil actuator mounted on

Wind barriers are nowadays commonly placed on bridges to protect vehicles from adverse cross- wind effects. In addition to this beneficial influence, wind barriers may adversely affect the bridge dynamic stability. This is particularly exhibited for

The flow around a heated circular cylinder and the wake behind it were studied in wind tunnel flow using two methods of anemometry, i.e., particle image velocimetry (PIV) and constant temperature anemometry (CTA) with a special technique using a rota

Wind-tunnel experiments are carried out to analyze the influence of wind-barrier porosity and height on aerodynamic and aeroelastic characteristics of wide long-span cable-supported bridges. The experiments are carried out on sectional models of the

Wind-tunnel experiments were carried out to study the influence of wind barriers on the flutter susceptibility of a bridge-deck section. This was performed on the model of a streamlined bridge-deck section equipped with various wind barriers. The win

A small-scale wind turbine model was designed and manufactured to study its aerodynamic thrust force and the harvested flow energy. To provide a good understanding of the aerodynamics of the small-scale wind turbine at the low Reynolds number, the pe

An experimental study of an aeroelastic behavior of bridge deck under influence of the wind is carried out in a wind tunnel. Particular attention is paid to seldom analysed influence of the traffic upon the aeroelastic coefficients, known as flutter
