Sažetak
The aim of this study is to investigate the possibilities of protecting the vehicles on viaducts in parts of the newly reconstructed Rijeka-Zagreb highway. The effects of wind barrier porosity on a flow field at the viaduct Bukovo and at the viaduct Hreljin are presented in this paper. Experiments were carried out in the Boundary Layer Wind Tunnel of CRIACIV in Prato, Italy. The flow field on the road plane was measured using the Particle Image Velocimetry (PIV) technique. The model was exposed to a turbulent oncoming flow generated using a grid positioned at the inlet of the wind tunnel test section. The improvement of the conditions of comfort on the investigated region due to the introduction of the barriers can vary conspicuously, due to the variation of some parameters.
