Abstract
U ovom radu prikazan je proračun spiralnog kućišta proizvoljnog presjeka za radijalne centrifugalne pumpe. Proračun je proveden za tri različita tipa kućišta: kružni, kišna kap i trapezni. Korištenjem programskog paketa Octave dobivene su dimenzije presjeka pomoću kojih su napravljeni 3D modeli kućišta u CAD programu. Modeli kućišta su zatim korištenjem programskih paketa Ansys/Fluent kombinirani s geometrijom postojećeg rotora [1] i na njima je izveden numerički proračun turbulentnog strujanja metodom kontrolnih volumena. Kako bi rezultati bili usporedivi, za sva tri oblika presjeka je korišten isti oblik jezičca, isti kut zakreta, te ista udaljenost izlaznog presjeka od centra rotacije. Izlazni presjeci su istih dimenzija kao i presjeci pojedinih kućišta na 360°. Za sve tipove kućišta su korištene iste početne postavke mreže kontrolnih volumena, a razlike u broju kontrolnih volumena i razlike u rezultatima su isključivo posljedica oblika presjeka.
Abstract (english)
In this work the dimensioning of spiral casings with arbitrary cross-sections was done. Chosen cross-sections were circular, raindrop and trapezoid shape. Using dimensions of the cross sections automatically generated by Octave, 3D CAD models of mentioned volute casings were made. Given volutes were then combined with the existing rotor [1] using Fluent/Ansys, and numerical analysis using finite volume method was performed. For the purpose of analogy of all modelled volutes, the shape of the cutwater for each volute was the same, as was the angle of the curved outlet of the casings and the distance from the outlet to the centre of rotation. Outlet cross sections shapes are the same as the cross section shapes for circumferential angle of 360°. For all volutes, the same boundary conditions were used when creating finite mesh, so that any distinctions in quantity of finite volume cells and analysis results are outcome solely from cross section shape of volute.
