Abstract
Tato diplomová práce se zabývá experimentálním měřením úplavu dvou modelů předního křídla týmu studentské formule. Cílem
práce byl zisk rychlostní a tlakových polí v okolí modelu a následné provedení validace simulací poskytnutých tímto týmem. Měření
bylo provedeno pomocí stereoskopické uspořádání metody Particle
Image velocimetry (PIV, česky také integrální laserová anemometrie) ve větrném tunelu katedry energetických zařízení. Pro účely
experimentu byly vyrobeny modely velikostně uzpůsobené použitému větrnému tunelu tak, aby došlo k eliminaci vlivu mezních vrstev
vznikajících na stěnách tunelu. Výsledky experimentu byly použity
pro validaci dodaných simulací a jsou popsány v této práci.
This master's thesis focuses on experimental measurement of the flow behind two front wing models of the student formula team. The goal of the work was to obtain velocity and pressure fields around the model and subsequently validate the simulations provided by this team. The measurement was performed using the stereoscopic setup of the Particle Image velocimetry (PIV) method in the wind tunnel of the Department of Power Engineering Equipment. For the purposes of the experiment, models dimensionally adapted to the used wind tunnel were manufactured so that the influence of the boundary layers forming on the tunnel walls could be eliminated. The experiment results were used to validate the provided simulations and are described in this thesis.
