Özet
In this research, numerical simulations of turbulent flow in a modified parabolic trough solar
collector and novel design regarding the inserted fins along the absorber tube was carried
out. These fins were inserted as repeat sets, and each set has an increasing height of fins. The
3D simulations were conducted based on the finite volume approach utilizing ANSYS
FLUENT. The obtained data are displayed in two different sections. In the first section,
investigations were carried out to show impacts of the number of inserted fins on PTC’s
thermal performance. Five different models with two, three, four, five and six numbers of
localized fins were analyzed and compared with the smooth reference model. The findings
exhibit that the thermal performance of all modified models within the tested range of Re is
greater than that of the reference model. In addition, the sixth model with six inserted fins
has a maximum thermal performance of 1.4. In the second section, different cross-sectional
areas of inserted fins including circular, elliptical, and square were examined. For the sixth
model, findings reveal that the maximum thermal performance for circular, elliptical and
square cross-sectional fins is 1.4, 1.31, and 1.26, respectively, at Re=4000.
