- Design of Experiments to Optimize the Thermal Performance of Finned Absorber Tubes in Parabolic Trough Collectors Raghad Alazawi Ahlem Houcine Ramla Gheith Heat Transfer ABSTRACT This paper outlines the thermal performance of parabolic trough collectors with internally finned absorbers using computational tools. The main purpose of this study revolves around the thermal improvement procedures for an absorber tube containing 12 long fins and Syltherm‐800 as working fluid. In more detail, to optimize the performance of the finned absorber tube, various fins' thickness (1–6 mm) and length (2–20 mm) configurations are examined with different volume flow rate (VFR) values (50–250 L/min) using computational fluid dynamics simulation. The outcomes are elucidated in connection with the thermal heat flux, pressure drop, and thermal efficiency. A full factorial design of experiments framework has been applied to pinpoint the most influential factors affecting the thermal enhancement of the parabolic trough solar system. In light of the ultimate findings, the employment of an internally finned absorber leads to an optimum thermal efficiency enhancement for a 6‐mm fin thickness, 20‐mm fin length, and 50‐L/min VFR. 10.1002/htj.70139 http://onlinelibrary.wiley.com/termsAndConditions#vor
