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

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