Abstract

This study numerically investigated the cooling effect, energy, and exergy analyses of twisted tapes with different pitch ratios (3, 4, and 5), widths (5, 7.5, and 9.5 mm), and thicknesses (0.5, 1, and 1.5 mm) on PV/T systems between Reynolds numbers of 500 and 1900. The research revealed a positive correlation between surface temperature and both thickness and pitch, but width showed a negative correlation with surface temperature. The maximum measured PV/T surface temperature was 320.437 K, and the minimum was 307.929 K. The thermal efficiency declined as the thickness, pitch, and width increased. The maximum thermal efficiency reached 59.35%. The highest Performance Evaluation Criteria (PEC) value of 1.535 was obtained with a width of 9.5 mm, a pitch ratio of 3, a thickness of 0.5 mm, and a Reynolds number of 500. The exercise evaluations revealed the advantageous impact of including a twisted tape insert in a PV/T system. The maximum electrical efficiency of exergy was 13.77%, while the maximum thermal efficiency of exergy was 1.59%. The RSM (Response Surface Methodology) was used to analyze the 405 numerical data acquired. Based on the analyzed parameters, equations were produced that may be applied to future geometries.
