This paper has analysed the effect of the utilization of internal finned tubes for the design of parabolic trough collectors with computational fluid dynamics tools. Our numerical approach has been qualified with the computational estimation of reported experimental data regarding phenomena involved in finned tube applications and solar irradiation of parabolic trough collector. The application of finned tubes to the design of parabolic trough collectors must take into account features as the pressure losses, thermal losses and thermo-mechanical stress and thermal fatigue. Our analysis shows an improvement potential in parabolic trough solar plants efficiency by the application of internal finned tubes.
► Parabolic trough collectors life improvement by internally finned tubes.
► Solar thermal oil degradation reduction by homogenization of temperature profile in parabolic trough collectors.
► Efficiency enhancement of parabolic trough collectors by finned tubes.
► CFD analysis of finned parabolic trough collector tubes.
