Abstract
U ovom završnom radu izvršena je analiza triju puhala s različitim karakteristikama te u različitim uvjetima rada. Pomoću grafičke analize dobivenih rezultata uočen je postupni rast masenog protoka što ukazuje na povećanje kapaciteta puhala s promjenom radnih uvjeta. Također, uočeno je da gubici energije imaju pozitivan trend s promjenom radne točke odnosno s povećanjem tlaka. Usporedba idealne i stvarne snage ukazuje na sve veću nejednakost između teorijske i stvarne vrijednosti snage s povećanjem brzine vrtnje turbopuhala te to može ukazati na aerodinamičke i termalne neefikasnosti puhala pri visokim radnim režimima. Ova analiza pruža ključne uvide za razumijevanje kako treba razmišljati ako se želi ići prema poboljšanju dizajna, operativnih procedura, uvjeta rada, a sve u svrhu minimiziranja gubitaka i povećanja efikasnosti puhala.
Abstract (english)
In this thesis, an analysis of three blowers with different characteristics and under varying operating conditions and loads was conducted. A graphical comparison of the obtained results revealed a positive increase in mass flow rate, indicating an increase in blower capacity with changes in operating conditions. Additionally, it was observed that energy losses exhibit exponential growth with changes in the operating point, i.e., with increasing pressure. The comparison between ideal and actual power indicates an increasing disparity between the theoretical and actual power values with an increase of the rotation speed, which may suggest aerodynamic and thermal inefficiencies in the blowers at high operating conditions. This analysis provides key insights for understanding how to think about improvements in design, operational procedures, and working conditions, all aimed at minimizing losses and increasing blower efficiency
