Obliczenia przepływu przez stopnie turbin parowych realizuje się zwykle przy założeniu symetrii i periodyczności obwodowej geometrii dla określonych warunków brzegowych. W ten sposób, poprzez zastąpienie obszaru obliczeniowego obejmującego cały wieniec kierowniczy bądź wirnikowy obszarem zredukowanym do jednego kanału w każdym z wieńców skraca się w sposób zdecydowany czasy żmudnych obliczeń numerycznych...
The article presents the methodology of determining loss and flow rate coefficients, which are usually used in the process of steam turbine blading system design. In the article, the above flow coefficients were determined from CFD calculations based on the Reynolds averaged Navier-Stokes equations and verified in experimental tests. The calculations were performed in steady-state and unsteady variants,...
