| الوصف: | U ovome radu prikazane su hidrauličke analize protočnosti pod utjecajem različitih oblika poprečnih presjeka i vrste obloženosti kanala. Prilikom analize različitih oblika poprečnih presjeka izrađen je hidraulički proračun za jednoliko stacionarno tečenje za trokutni, pravokutni, trapezni i polukružni oblik poprečnog presjeka kanala. Prvom provedenom hidrauličkom analizom uspostavilo se da je, u pogledu protočnosti kanala, najpovoljniji polukružni oblik poprečnog presjeka kanala. U drugoj hidrauličkoj analizi promatrane su različite vrste obloženosti stijenki kanala te se u tu svrhu također proveo hidraulički proračun za jednoliko stacionarno tečenje u kojem su promatrane različite obloge kanala, odnosno koeficijenta hrapavosti na protočnost. Provedena analiza pokazala je kako veći koeficijenti hrapavosti daju manju protočnost u kanalu i obrnuto. Samim time, prilikom dimenzioniranja kanala, odnosno hidrauličkog proračuna, potrebno je uzeti u obzir odgovarajući poprečni presjek kanala te vrstu obloženosti kanala kako bi dimenzionirani kanal bio najpovoljniji u pogledu što manjih hidrauličkih gubitaka i što veće propusne moći. This paper presents hydraulic analysis of flow in channels under the influence of various cross-sections and type of covering of the channel. During the analysis of different cross sections, a hydraulic design was made for uniform stationary flow for the triangular, rectangular, trapezoidal and semicircular cross-sectional shape of the channel. First performed hydraulic analysis established that the semicircular cross-section of the channel is the most favorable in terms of flow. In the second hydraulic analysis, various types of covering of the channel were observed and a hydraulic design for uniform stationary flow was carried out in order to observe different channel coverings, i.e. the coefficient of roughness. The analysis showed that higher coefficients of roughness give a smaller flow in the channel and smaller coefficients of roughness give a higher flow in the channel. In this case, when dimensioning the channel or the hydraulic design, the appropriate cross section of the channel and the type of covering of the channel should be taken into consideration so that the dimensioned channel is most favorable in terms of smaller hydraulic losses and greater flow in the channel. |
