Abstract
Rad se bavi analizom i usporedbom turboventilatorskih motora. Na temelju zadanih radnih parametara izrađen je termodinamički proračun za sva tri zadana turboventilatorska motora i sve njihove komponente (ventilator, turbokompresore, komoru izgaranja i turbine). Time su, za sve komponente, kao i cjelokupne motore, dobiveni sljedeći podaci: idealna i realna snaga, energijski gubici, energijska iskoristivost, eksergijski ulaz i izlaz, eksergijski gubici, eksergijska iskoristivost, korisna snaga. Ti su rezultati bili temelj za izvršavanje energijske i eksergijske analize. Provedene su analize rezultirale sljedećim zaključcima: korisne snage će biti veće što je veća potreba za pokrivanjem mehaničkih gubitaka motora. Također, što je veći maseni protok goriva, to će iskoristivost motora biti veća. Utvrđeno je i da je energija neovisna o utjecajima okoline, dok kod eksergije to nije slučaj, tj. porast okolne temperature će dovesti do većih eksergijskih gubitaka i manje eksergijske iskoristivosti motora.
Abstract (english)
The paper deals with the analysis and comparison of turbofan engines. Based on default working parameters, a thermodynamic calculation was made for all three given turbofan engines i all their components (fan, turbocompressors, combustion chamber and turbines). Thereby, they for all components, as well as entire engines, the following data were obtained: ideal and real power, energy losses, energy utilization, exergy input and output, exergy losses, exergy utilization, useful power. These results were the basis for the execution of the energy and exergy analysis. The analyzes carried out resulted in the following conclusions: the higher the useful power will be the need to cover mechanical engine losses. Also, the higher the mass flow of fuel, the more useful the engine will be. It was also established that energy is independent of influences of the environment, while this is not the case with exergy, i.e. an increase in the surrounding temperature will lead to greater exergy losses and less exergy utilization of the engine.
