20.500.12556/DKUM-82763 Numerično modeliranje dvofaznega toka v mali čistilni napravi diplomsko delo Numerical modeling of two phase flow in small wastewater cleaning plant V diplomskem delu je s pomočjo računalniške dinamike tekočin, opravljena numerična analiza dvofaznega toka v mali čistilni napravi. Predstavljene so geometrijske lastnosti ter vplivni parametri, kot tudi aeracija v mali čistilni napravi. V nadaljevanju je predstavljeno teoretično ozadje modeliranja. Izpeljana sta tudi ohranitvena zakona mase in gibalne količine. Izvedena je bila poliedrična mreža, analiza vplivnih parametrov pretoka in velikosti mehurčka zraka na aeracijo. Na koncu je bil računan indeks uniformnosti porazdelitve volumskega deleža zraka v mali čistilni napravi. Ugotovljene in predstavljene so optimalne razmere za opravljeno simulacijo. The presented diploma includes a preparation and abstraction of computational fluid dynamics in need to observe numerical analysis of two-phase flow in a small wastewater cleaning plant. Presented are geometric properties and influencing parameters, as well as aeration in a small wastewater cleaning plant. Diploma includes presentation of theoretical background in modeling computer fluid dinamics and the conservation laws of mass and momentum. A polyhedral mesh, analysis of the influencing parameters of flow and air bubble size on aeration was carried out. In the end, the computerized index of uniformity distribution of air volume fraction in a small wastewater cleaning plant. The optimal conditions for the completed simulation have been identified and presented. mala čistilna naprava računalniška dinamika tekočin ANSYS Fluent aeracija simulacija small wastewater cleaning plant computer fluid dynamics ANSYS Fluent aeration simulation true true false [Ž.
