Erroneous equations used to assess the performance of a solar pond
Abstract
With great interest, I examined the theoretical analysis section of the paper "Performance assessment of a solar pond with and without shading effect" by Mehmet Karakilcik, Ibrahim Dincer, Ismail Bozkurt, Ayhan Atiz, 65 (2013) 98-107 [1]. The numerical part of the study is based on shading area analysis in different solar pond zones. I believe an incorrect format of equation was used in calculating the shading length of the layers. Another part of the study is based on energy analysis of solar pond zones to determine the energy efficiencies of each zone. Also, I believe there are contradictions and wrong formats of equations in this part of the paper. The equations used to calculate the net solar energy which reached the surface of each layer (Qns) are incorrect. Also, the transmission function (hI) and coefficient of transmission (β), do not only contradict the ones referred to in the article, but are also in wrong formats.
