Özet

In recent years, the exploitation of energy resources at limits has sought an answer to the question how renewable energy could be used more efficiently. The aim of this study is to increase the thermal performance of parabolic trough collectors (PTC) by optimizing the system parameters by using response surface methodology (RSM). A staggered butterfly finned turbulator designed and manufactured specifically for the PTC system was used to improve heat transfer through the pipe. Efficiency was chosen as the response variable. The effects of the spacing of the turbulator fins, Reynolds number, and solar irradiance were investigated by the RSM. As a result, optimum values for thermal efficiency were obtained to be 9.44 cm for turbulator fin spacing, 821.21 for the Reynolds number, and 875.75 W/m(2) for solar irradiance. A CFD analysis was performed for the verification of the optimum results obtained, which revealed good agreement between the optimum values obtained experimentally and the results of the numerical analysis. In addition, an experimentally validated mathematical model represented by independent parameters is presented.
