20.500.12556/DKUM-87700 Primerjava med 1d in 3d cfd numerično simulacijo motornega prostora delovnega stroja diplomsko delo Comparison between 1d and 3d cfd numerical simulation of excavator underhood Namen zaključnega dela je primerjava med 1D in 3D CFD numerično simulacijo kompleksnega motornega prostora delovnega stroja. Zanima nas, ali je 1D CFD simulacija smiselna in dovolj natančna za nadaljni razvoj hladilnega sistema. CAD model delovnega stroja je bil uvožen v GEM3D ter primerno obdelan za izvoz v 1D model. 1D model je bil izdelan in simuliran v programski opremi GT-SUITE. Končna ugotovitev je, da trenutno GT-SUITE še ne premore obdelovati tako kompleksnih modelov, vendar ima zelo dobro podlago za obdelavo modelov v začetni fazi razvoja modela. The purpose of this thesis is to compare 1D CFD and 3D CFD numerical simulations of a complex excavator underhood. Question was, whether a 1D CFD simulation is meaningful and accurate enough for the further development of the cooling system. The CAD model of the working machine was imported into GEM3D and appropriately processed for export to a 1D model. 1D model was build and simulated with GT-SUITE software. The final conclusion was that, at the moment, GT-SUITE is not capable of handling such complex 1D models, but it provides a very good foundation for processing models in the initial stages of model development. motorni prostor delovni stroj 1D CFD primerjava med 1D in 3D CFD simulacijo GT-SUITE GEM3D GT-ISE CFD 1D model 3D model numerična simulacija underhood heavy machinery 1D CFD 1D and 3D CFD simulation comparison GT-SUITE GEM3D GT-ISE CFD 1D model 3D model numerical simulation true true false [T.
