20.500.12556/DKUM-26926 Utjecaj različitih tipova mreže na proces kavitacije u otvoru sapnice brizgaljke Influence of various mesh types on cavitation phenomena in the injection nozzle The evaporation of diesel fuel in the injection nozzle influences the injection characteristics and spray formation process significantly. In the presented paper the influence of various type of mesh on the cavitation phenomena is analysed. Since CPU (central processing unit) times are often high, partial models are used for the analysis. The numerical analysis is made for two types of fluid, diesel (D2) and biodiesel (B100), using computation fluid dynamic (CFD) program FIRE. The results are compared for various meshes and both types of fuel. The results show that higher pressure differences yield more cavitation in the injector nozzle holes and point out the importance of the structure of the mesh and its density. dizelsko gorivo numerično modeliranje tekočin mrežni sistem prostorskih koordinat kavitacija diesel cavitation true true false Slovenski jezik Angleški jezik Neznano 2012-06-01 08:40:00 2012-06-01 08:40:00 2022-04-15 03:42:56 2019-07-10 12:09:05 2011 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.436:532.528 15654422 0350-350X URN:SI:UM:DK:UER2RUJM http://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=111801 1 https://dk.um.si/Dokument.php?lang=slv&id=36127 Fakulteta za strojništvo 0 0 0
