Modeling and Simulation to Investigate the Thermal Efficiency of a Parabolic Solar Trough Collector with Absorber Tube Inserted Twisted Tape System

Öz

Concentrated solar power is one of the renewable energy sources in the world that can be utilized from solar energy by combining
and concentrating it. In this numerical study, computer software was used to investigate the parabolic trough collector consists
of a mirror and tube made of copper covered with a vacuum glass. The twisted tape made of aluminum is placed inside the tube
to generate swirl flow and turbulence around the axial centerline of the absorber tube with the working fluid. Water was used as
a working fluid with turbulent flow, the Reynolds number varied for the range of 2000 to 9000. To describe the present study,
continuity, momentum, and energy equations were used. The angle of inclination of the twisted tape has been taken into account
in six different values: 25 °, 33 °, 45 °, 50 °, 55 °, and 60 °. A study occurred in the city of Istanbul in Turkey with 41° latitude and
28.97° longitude for a periodic time from 9:00 am to 3:00 pm, for four different selected months, September, October, November,
and December. Results illustrated increasing in outlet temperature and heat transfer enhancement for six twisted tape angles
compared with the plain tube. The best angle of inclination of the twisted tape was found to be 50 degrees.
