20.500.12556/RUL-120206 Rapid detection of active nucleation sites in pool boiling experiments based on analysis of transient temperature fields It is well known, that water, when heated above its saturation temperature, boils. Anyone can observe boiling by simply pouring the water into a cooking pot and placing it onto the stove. Despite its virtual simplicity, the boiling process is a complex phenomenon governed by many underlying heat and mass transfer mechanisms. In-depth study of boiling process requires information about bubble departure and footprint diameter, nucleation frequency, nucleation site density and nucleation site distribution. Acquiring this information usually takes a lot of time and manual work during the post-processing phase. Development of robust and fast data processing algorithms is therefore highly appreciated by the scientific community. In this work, we developed new algorithm to detect active nucleation sites based on the transient temperature fields obtained by high-speed IR camera during saturated boiling experiments on thin metal foil. Results show that this method offers a robust and rapid detection of active nucleation sites, which can be later implemented in a more complex image processing algorithms. pool boiling high-speed IR thermography laser surface engineering image processing vrenje v bazenu hitrotekoča IR termografija laserski inženiring površin strojna obdelava slik true false false Angleški jezik Slovenski jezik Drugo 2020-09-17 08:18:52 2020-09-17 08:18:53 2022-09-01 03:57:53 0000-00-00 00:00:00 2020 0 0 Str. 103-110 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.24:004.946:681.518.52(045) 28556803 27402243 RAZ_Pecnik_Tim_2020.pdf RAZ_Pecnik_Tim_2020.pdf 1 44E95A48693F95DB52EFD9B62F98807A c67298155b55d23738ef1548307e55b9eb3d913dfede7ca5e6311c82abdee809 06d0350a-a1ba-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=134986 Fakulteta za strojništvo 0 0 0
