20.500.12556/RUL-186586 Eksperimentalna analiza šob in obratovalnih parametrov pri tvorbi umetnega snega Experimental analysis of nozzles and operating parameters in artificial snow production Zaradi globalnega segrevanja in dviganja snežne meje vse več nižje ležečih smučišč za zagotavljanje zadostne količine snega uporablja sisteme za izdelavo umetnega snega. V diplomski nalogi smo v klimatski komori eksperimentalno analizirali vpliv ključnih parametrov na kakovost in količino umetno narejenega snega, pri čemer smo se osredotočili na pnevmatske šobe in obratovalne pogoje. Šobe, uporabljene v eksperimentih, so bile izdelane s tehnologijo 3D tiskanja, ki se je izkazala kot primeren in učinkovit pristop za njihovo izdelavo. V okviru eksperimenta smo sistematično spreminjali tlak vstopnega zraka, temperaturo vode, temperaturo okoliškega zraka ter geometrijo šobe. Kakovost nastalega snega smo po vsakem testu ovrednotili s kalorimetrično metodo. Rezultati so pokazali, da ima največji vpliv na kakovost snega tlak vstopnega zraka, medtem ko temperatura okoliškega zraka pomembno vpliva tako na kakovost kot na količino nastalega snega. Geometrija šobe se je prav tako izkazala kot ključen parameter, ki bistveno vpliva na lastnosti proizvedenega snega. Due to global warming and the rising snow line, an increasing number of lower-altitude ski resorts rely on artificial snowmaking systems to ensure sufficient snow coverage. This thesis presents an experimental analysis in climatic chamber of the key parameters affecting the quality and quantity of artificially produced snow, with a focus on pneumatic snow guns and their operating conditions. The nozzles used in the experiments were produced using 3D printing technology, which proved to be a viable and effective manufacturing approach for this application. During the experiment, the inlet air pressure, water temperature, ambient air temperature, and nozzle geometry were systematically varied. The quality of the produced snow was evaluated after each test using a calorimetric method. The results showed that inlet air pressure has the greatest influence on snow quality, while ambient air temperature significantly affects both the quality and quantity of the produced snow. Nozzle geometry also proved to be a critical parameter with a substantial impact on the properties of the artificially produced snow. umetni sneg klimatska komora šoba ledeni kristali prenos toplote nukleacijska jedra artificial snow climate chamber nozzle ice crystals heat transfer nucleation core true false false [N.
