    Design of particle image velocimetry system for the wind tunnel of University of Žilina
    (University of Zilina, 2022) Pancurák, Daniel; Pecho, Pavol
    Due to always ongoing innovation in research ability of our research facility it was decided to innovate already existing wind tunnel by implementing system of Particle Image Velocimetry. Main goal of this thesis is to create sufficient technical solution for implementation of Particle Image Velocimetry measuring systems. This system will allow creation of accurate measurements of aerodynamic forces and visualise airflow direction and its strength. Implementation of this system consists of designing sufficient structure to allow proper mount and movement of laser light source, which will be high power laser and mount for camera, which will be used to capture images of airflow of measured parts. In terms of laser stand, the main goal was to simplify the construction to decrease costs of structure and to create room for future upgrades and implementations of possible motorisation and electronic controls. For main construction were chosen steel profiles with square cut and size of 30x30 mm to match already existing construction used to stabilise measured part in test chamber. Implementation of this system of measurement will increase research abilities and it will create room for more projects, which depend on this method of measurement. Particle Image Velocimetry has wide range of usage from automotive industry through aviation to designing of spray nozzles. This will create large research opportunities for other facilities and professionals from different parts of industry, since this technology will be one of the first implemented into wind tunnel in Slovakia.
