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 mlaza vode nakon izlaska s mlaznice, (iii) tečenje sa slobodnom vodnom površinom na lopaticama Peltonove turbine te (iv) raspršeno dvofazno tečenje na kućištu Peltonove turbine. S obzirom da postoji cijeli niz različitih formula i preporuka za dimenzioniranje, cilj ovoga rada bio je objediniti i dati pregled istih na jednom mjestu. Istraživanje za potrebe ovoga rada proizašlo je iz prethodnog istraživanja za potrebe izrade diplomskoga rada.
The most used parameter in rock engineering practice is the Uniaxial Compressive Strength (UCS). It is often estimated on the field or trough Index-to-strength conversion factors proposed by various researchers for a specific rock type. The research presented in the paper involved field estimation of Uniaxial Compressive Strength using Schmidt rebound hammer and Point Load laboratory testing on limestone rock samples. The results of the estimated UCS were compared to the Uniaxial Compression Strength laboratory testing results on limestone specimens taken from the same location, in order to compare corresponding UCS of limestone rocks. These results can contribute to better estimation of the local design parameters, when direct determination of the UCS in the laboratory is not possible, rather than adopting the values from around the world case studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
