Abstract
U ovom diplomskom radu napravljena su numerička ispitivanja centrifugalne crpke koristeći software Solidworks, zatim ICEM CFD, te Ansys Fluent. Geometrija je napravljena prema nacrtima centrifugalne crpke sa eksperimentalnog ispitivanja na Tehničkom Sveučilištu Braunschweig. Ona je zatim podijeljena u tri zone koje su zasebno omrežene i povezane u Fluentu. Koristeći dostupne podatke sa eksperimentalnog ispitivanja, zadani su rubni uvjeti crpke i izvršene su simulacije protoka vode kroz crpku. Kao rezultat toga dobivena je ovisnost specifične snage o koeficijentu protoka uz promjenu turbulentnih modela u samom programu. Nakon toga pristupilo se simulaciji pojave rotirajuće kavitacije u području rotora crpke. Dobiveni rezultati ove simulacije pokazuju ovisnost specifične snage o kavitacijskom broju. Zbog nedostatka preciznih podataka o rubnim uvjetima u crpki i nedostataka točnih dimenzija same crpke, dobiveni rezultati pokazuju približne vrijednosti dobivene u eksperimentalnom ispitivanju uz određena odstupanja.
Abstract (english)
In this master thesis numerical studies of centrifugal pump have been carried out using software Solidworks, then ICEM CFD and Ansys Fluent. Geometry has been made according to centrifugal pump designs from experimental studies on Technical University of Braunschweig. After geometry has been made the pump was divided into three zones which have been meshed and appended in Fluent. By using available data from experimental studies, boundary conditions have been set and simulations of water flow through pump have been carried out. As a result, curve of pressure rise coefficient in dependence with flow coefficient has been made, with different turbulent models in Fluent. After that, simulation of rotating cavitation, in impeller area has been carried out. The results of this simulation shows pressure rise coefficient in dependence with cavitation number. Because of insufficent boundary conditions data in centrifugal pump and lack of precise geometry dimensions itself , the results are simmilar to experimental but there are some differences.
