20.500.12556/DKUM-23156 Nestacionarni tok tekočine v cevi z loputo UNSTEADY FLOW OF FLUID IN THE PIPE WITH THE BUTTERFLY VALVE V pričujoči specialistični nalogi smo s pomočjo računalniškega programa na osnovi računalniške dinamike tekočin izvedli stacionarno in nestacionarno analizo tokovnih razmer geometrijskega modela razcepne cevi z loputo. Za geometrijski model je izdelana ustrezna mreža (diskretizacija modela) ter definirani so robni pogoji v zaključku naloge pa je podana ocena rezultatov ter vpliv turbulentnega toka v cevi za loputo. Računalniška simulacija je izvedena s programskim orodjem ANSYS CFD. With the help of numerical methods based on the computational fluid dynamic we try in the presented postgraduate work to calculate steady and unsteady flow analysis of bifurcation pipe with the valve. For the geometrical model an appropriate model discretization was performed and boundary conditions were defined. At the end of the work we evaluate the results and asses the influence of turbulent flow after the valve. Calculation was performed with the ANSYS CFD soft ware. turbulentni tok CFD Računalniška dinamika tekočin numerično modeliranje toka tekočin turbulent flow CFD Computational fluid dynamic numerical modeling of fluid flow true true false [A.
