Abstract
Primarni cilj ovoga rada analiza je turbulentnog toka nekompresibilna fluida u centrifugalnoj crpki. Korišten je rješavač otvorenog koda, OpenFOAM, te su rezultati za analizirani model crpke uspoređeni s pripadnom eksperimentalnom izvedbom centrifugalne crpke Tehničkog fakulteta u Beču (TU Wien). Nakon upoznavanja strukture te principa rada centrifugalne crpke na temelju dostupne dokumentacije (TU Wien) izrađen je CAD model kojeg se potom 3D modeliralo, a zatim diskretiziralo mrežom tetraedarske strukture koristeći ANSYS Workbench Mesh. OpenFOAM-ov rješavač za stacionarno strujanje SRFSimpleFoam korišten je za provedbu simulacija turbulentna strujanja nekompresibilna fluida, a za vizualizaciju rezultata izvršenih simulacija korišten je ParaView. Krivulje crpke izvršenih SRFSimpleFoam simulacija te Particle Image Velocimetry ispitivanja (TU Wien) najbolji su prikaz odstupanja dviju metoda. Kvaliteta numeričke mreže korištene prilikom CFD analize glavni je faktor odstupanja, te je teza kako se eksperimentalna ispitivanja ne mogu nikada u potpunosti zamijeniti potvrđena.
Abstract (english)
Primary goal of this thesis is analysis of turbulent flow of incompressible fluid in centrifugal pump. Open-source solver, OpenFOAM, was used and results for analysed model of pump were compared with associated experimental results of centrifugal pump made on Tehnical University Wien (TU Wien). After getting to know the structure and working principle of centrifugal pump based on available documentation (TU Wien) CAD model was made, after which it was 3D modelled, and than discretizated by tetrahedral structure mesh using ANSYS Workbench Mesh. OpenFOAM`s solver for steady flow SRFSimpleFoam was used for simulating turbulent flow of incompressible fluid and ParaView was used for visualisation of simulation results. Pump curves are the best representation for deviation of two methods,SRFSimpleFoam simulations and Particle Image Velocimetry study (TU Wien). Quality of numerical mesh used by CFD analysis is the main factor of deviation between the two methods, which confirms the thesis that experimental studies can`t be completely replaced.
