20.500.12556/RUL-101774 Eksperimentalno določanje povezave med pretokom zraka in vode skozi režo Experimental study of correlation between air and water flow rate through a clearance Vsak proizvod, v katerem se pretaka medij, mora poleg osnovne funkcije zagotavljati tudi da pretočni medij ne izteka, zato je preizkušanje tesnosti v proizvodnji nujno potrebno. Poznavanje zakonov pretoka tekočin skozi majhne reže je ključno pri izvajanju teh preizkusov. Ker so preizkusi z zrakom stroškovno in praktično bolj učinkoviti kot tisti z vodo, je pomembno poznati relacijo med pretokom obeh medijev pri enakih pogojih. V delu so predstavljene meritve pretoka vode in zraka skozi iglični ventil, ki simulira majhno režo. Določene so tudi vzporednice med pretokom obeh medijev in pojasnjeni parametri, ki vplivajo na velikost pretoka skozi režo. In addition to its basic function, every product that incorporates fluid flow must also ensure that the fluid does not leak out, making leak testing crucial in production.The knowledge of physical phenomena behind fluid flow through a clearance is essential when establishing the fluid-tightness of a product. Since leak testing with air is more cost efficient and practical than using water, the correlation between the flow rate of the two fluids at similar conditions is very important. This paper includes measurements of water and air flow rate through a needle valve, that was used to simulate a small clearance. The parallels between the flow rate of both fluids are established and the factors, that influence the flow rate, are given. tok tekočine pretok reža iglični ventil puščanje fluid flow flow rate clearance needle valve leakage true false false [J.
