Abstract
Zaštitna rešetka postavlja se ispred hidroelektrane te ima ključnu ulog u zaštiti hidroelektrana od krupnih predmeta koji ju mogu oštetiti kao i zaštiti riba te ostalog životinjskog svijeta od ulaska u turbinu. U ovom diplomskom radu istražuje se utjecaj poprečnog presjeka zaštitne rešetke na hidrauličke gubitke. Izrađene su numeričke simulacije pomoću programskog alata OpenFOAM te su ispitani različiti nagibi i 4 različita poprečna presjeka. Rezultati ovog rada ukazuju da je potrebno pomno analizirati i odabrati koji poprečni presjek zaštitne rešetke odabrati. Optimizacija poprečnog presjeka zaštitne rešetke može povećati iskoristivost turbina u hidroelektrani i smanjiti hidrauličke gubitke, što rezultira poboljšanom učinkovitošću sustava.
Abstract (english)
Trash rack is installed in front of the hydroelectric power plant and plays a crucial role in safeguarding hydroelectric facilities from large objects that could damage them, as well as protecting fish and other wildlife from entering the turbine. This master’s thesis investigates the impact of the cross-sectional area of trash rack on hydraulic losses. Numerical simulations were conducted using the OpenFOAM software tool, examining different angles and four different cross-sections. The results of this study indicate the need for careful analysis and selection of appropriate cross-section for the trash rack. Optimizing the cross-sectional shape of the trash rack can increase the efficiency of turbines in the hydroelectric power plant and reduce head losses, resulting in improved system efficiency.
