Abstract
U ovom radu su opisane i primijenjene dvije metode hidrauličkog proračuna radnog kola aksijalne pumpe: metoda uzgonskih sila i metoda ravne profilne rešetke. Za provedbu proračuna su korišteni programski paketi Python, gmsh i OpenFOAM. Hidrodinamičke karakteristike krilnih profila za oblikovanje lopatica radnog kola odredene su numeričkim simulacijama strujanja uida u OpenFOAMu, a proračunska mreža je napravljena u programskom paketu gmsh. Konačni oblik lopatice je definiran u programskom paketu Python. Cijeli postupak proračuna je automatiziran. Kako bi se provjerila točnost proračuna, provedene su numeričke simulacije strujanja fluida kroz pumpu. Korišten je proračun strujanja fluida pomoću metode pokretnog koordinatnog sustava. Rezultati numeričkog proračuna pokazuju da metoda ravne profilne rešetke daje točnije rezultate u odnosu na metodu uzgonskih sila. Rezultati simulacija također pokazuju da oba radna kola aksijalne pumpe dobivena provedenim hidrauličkim proračunom postižu veću visinu dobave od zadane.
Abstract (english)
Two procedures for the hydrodynamic calculation of the rotor of axial ow pump has been described and applied in this thesis: buoyancy forces method and cascade method. Calculations were performed using Python, gmsh and OpenFOAM program packages. The required characteristics for shaping the rotor blades are determined by numerical uidow simulations in OpenFoam, and the mesh is made in the gmsh program package gmsh. The final shape of the blade is defined in Python. The entire calculation process is automated. In order to check the accuracy of the calculation, a simulation of uidow through the pump was carried out. Fluid ow calculation was performed using the Multiple Reference Frame approach. The results of the numerical calculation show that the cascade method gives more accurate results than the buoyancy forces method. The results of the numerical calculation show that the required hydraulic characteristics for both of the axial pump rotors have been met.
