20.500.12556/DKUM-92870 Merjenje porazdelitve velikosti kapljic na šobi s pomočjo laserskega sistema magistrsko delo Measurement of droplet size distribution on the nozzle using a laser system V magistrskem delu smo preučevali sistem VisiSize za merjenje porazdelitve velikosti in hitrosti delcev. Postavili smo merilno progo in izvedli eksperimentalne meritve na razpršilni šobi. Uporabili smo različne masne pretoke ter tlake atomizacijskega zraka in zraka za oblikovanje vzorca, ter spremljali njihov vpliv na lastnosti delcev. Ugotovili smo, da tlaka zraka pomembno vplivata na velikost in hitrost delcev, medtem ko ima masni pretok manjši vpliv. Izvedli smo tudi meritve na različnih razdaljah od šobe. Izkazalo se je, da z ustreznimi nastavitvami lahko zagotovimo zanesljive in ponovljive rezultate, ki pomembno prispevajo k razvoju in optimizaciji razpršilnih naprav. This master's thesis investigates the VisiSize system for measuring the distribution of particle size and velocity. A measurement setup was constructed, and experimental tests were performed on a spray nozzle. Various mass flow rates, atomization air pressures, and pattern air pressures were applied to observe their influence on particle characteristics. The results showed that air pressures significantly affect droplet size and velocity, while the mass flow rate has a smaller effect. Measurements were also conducted at various distances from the nozzle. The findings show that with appropriate settings, it is possible to achieve reliable and repeatable results that significantly support the development and optimization of spray devices. velikost kapljic velikost delcev merilni sistem laserski sistem slikovna analiza droplet size particle size measurement system laser system image analysis true true false [S.
