Pregled dimenzioniranja Peltonove turbine
Zbornik radova, 2021 Unutar ovoga rada biti će dan pregled dimenzioniranja Peltonove turbine. Kako se pri radu turbine javljaju vrlo složeni uvjeti tečenja i fizikalni procesi, optimizacija i samo dimenzioniranje ovakvog sustava je izazov. Primjerice, u radu turbine javljaju se četiri režima tečenja: (i) stacionarno tečenje u uzvodnim i dovodnim cijevima, (ii) slobodni pad
