20.500.12556/RUL-139869 Razvoj eksperimentalne proge za mikroskopsko in termografsko analizo zmrzovanja vodne kapljice Development of an experimental setup for microscopic and thermographic observation of water droplet freezing V zadnjih letih so različni načini obdelave površin, ki preprečujejo akumulacijo sreža in ledu, tema številnih raziskav, saj imajo obdelane površine zaradi svojih lastnosti, potencial za aplikacije na različnih področjih. V okviru te zaključne naloge smo zasnovali eksperimentalno progo za mikroskopsko in termografsko analizo zmrzovanja vodne kapljice. V programu SolidWorks je bila zasnovana komora, uporabljena za analizo zmrzovanja vodnih kapljic na različnih površinah. Zasnovano komoro, umeščeno v eksperimentalni progi, smo preko meritev pod mikroskopom in infrardečo kamero ovrednotili. Meritve, opravljene pod mikroskopom, prek zajema posnetkov s hitrotekočo kamero kažejo vpliv okolice na sreženje površine. Pri termografski analizi smo podrobno preučili proces rekalescence. Dokazali smo tudi, da je mogoče s hitrotekočo infrardečo kamero popisati krajevne in časovne spremembe temperatur tekom procesa zmrzovanja vodne kapljice. In recent years, different methods of treating surfaces, that prevent accumulation of snow and ice, have been the subject of several researchers due to improved properties of treated surfaces and potential applications in various fields. In this thesis, we designed an experimental setup for microscopic and thermographic analysis of water droplet freezing. A chamber designed in SolidWorks, was used to observe the freezing of water droplets on different surfaces. The designed chamber was placed in the experimental setup and evaluated through measurements under a microscope and IR camera. Measurements carried out under the microscope, through the capture of images with a high-speed camera, show the influence of the environment on the appearance of frost on the surface. The process of recalescence was studied in detail. It was demonstrated, that it is possible to detect local and temporal temperature changes during the process of water droplet freezing, with a high-speed infrared camera. proces zmrzovanja kapljice kontaktni kot kapljice mikroskopska analiza rekalescenca termografska analiza droplet freezing process contact angle microscopic analysis recalescence thermographic analysis true false false [R.
