摘要: Abstract In this study, the use of internal fins in parabolic trough collectors operating with gas working fluids is examined. Air, helium and carbon dioxide are investigated fluids, while Eurotrough ET-150 examined solar collector. The design simulation collector performed commercial software Solidworks Flow Simulation. lead to higher thermal efficiency but also pressure losses; something very important for fields Concentrated Power Plants. Thus, energetically exergetically order take into account increase useful output simultaneous greater need pumping power. Various fin lengths finally 10 mm was proved be most appropriate exergetically. fluid comparison, efficient all cases. performs better up 290 °C, best choice temperature levels. Moreover, optimum mass flow rate 0.03 kg/s other value 0.015 kg/s seems satisfying results.
