20.500.12556/DKUM-87132 Cavitation erosion modelling comparison of different driving pressure approaches In this paper we compared different driving pressure approaches to calculate the cavitation potential energy from a source, which is transferred to a surface. The first approach used the reference pressure, the second approach used the pressure calculated at each timestep with no averaging, the third approach used the averaged pressure values from all timesteps included in one shedding cycle, and the last approach used pressure values from the steady state simulations results. The results show that for all formulations the averaged pressure values and steady state pressure values give similar results in terms of mean potential power distribution on the hydrofoil surface as in absolute values. The reference pressure approach gave similar results for the derivative and divergence formulation while for the source term the mean potential power distribution on the hydrofoil surface differs and the maximums were near the leading edge. The approach where we used no pressure averaging gave adequate results in terms of mean potential power distribution but differs from other approaches in absolute values which were considerably lower for all potential power formulations. cavitation erosion potentional driving pressure numerical simulations kavtiacija erozijski potencial vozni tlak numerične simulacije true false true DAAAM International Vienna Angleški jezik Slovenski jezik Znanstveno delo 2024-02-21 15:09:57 2024-02-21 15:17:23 2025-03-27 13:52:42 0000-00-00 00:00:00 2023 0 0 Str. 233-244 št. 2 Letn. 22 June 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-06-01 519.6:620.1 155289603 10.2507/IJSIMM22-2-639 1726-4529 Kevorkijan-2023-CAVITATION_EROSION_MODELLING_-.pdf Kevorkijan-2023-CAVITATION_EROSION_MODELLING_-.pdf 1 679F56DBF87F91AC0B886973F58202CC 22a3946bef614ba56c0d6c7ecba7b6541bcc29a2775c2b5e306743ee6bdd0ef5 bae698d3-d0c3-11ee-bf60-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176346 https://www.ijsimm.com/view_articles.html 0 e69ad680-d0c3-11ee-bf60-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176347 Fakulteta za strojništvo Fakulteta za energetiko 0 0 0
