Performance test in semispherical solar collectors with discontinuous absorber

[摘要] This work aims at characterizing the performance of a solar thermal collector with non-continuous absorber area. The study bases its development on the classical performance method for flat-plate collectors, but using the effective absorber area that intercepts solar radiation. The work determines not only thermal efficiency of the solar collector but corrected overall thermal losses coefficient for the specific geometric design. (C) 2019 Elsevier Ltd. All rights reserved.
