Abstract

Ovaj izvještaj opisuje stvaranje, verifikaciju i primjenu modela prijenosa topline koji je implementiran u softverskom paketu Simulink. Model procjenjuje performanse linearnog prijemnika u paraboličnom kolektoru za solarnu energiju. Izvještaj obuhvaća uključivanje jednadžbi prijenosa topline, termodinamičkih jednadžbi, optičkih svojstava i relevantnih parametara unutar modela. Također, obrađuje pretpostavke i ograničenja modela, kao i specifično ponašanje koje model pokazuje. U okviru modela, analiziran je utjecaj masenog protoka radnog medija kroz linearni prijemnik na njegovu temperaturu. Izvedena je simulacija puštanja u pogon tijekom jutarnjih sati kako bi se prikazalo vrijeme potrebno za zagrijavanje radnog medija na optimalnu temperaturu. Također, istražen je utjecaj naoblake na rad solarnog polja.

Abstract (english)

This report presents the creation, verification, and application of a heat transfer model incorporated within Simulink. The model assesses the performance of a linear receiver in a parabolic trough solar collector. The report covers the inclusion of heat transfer equations, thermodynamic equations, optical properties, and relevant parameters within the model. Additionally, it addresses the assumptions and limitations of the model, as well as specific behaviors exhibited by the model. Within the model, the impact of the mass flow rate of the working fluid through the linear receiver on its temperature was analyzed. A simulation of the start-up during the morning hours was conducted to illustrate the time required to heat the working fluid to the optimal temperature. Additionally, the influence of cloud cover on the performance of the solar field was investigated.
