Turbulent flow of oil based hybrid nanofluid within an absorber tube of concentrated solar system has been evaluated in this article. To concentrate the solar irradiation, the parabolic plate has been located below the tube and variable heat flux was considered as the boundary condition of the tube. The presence of a turbulator within the circular tube causes secondary flow to increase. Both thermal (Sgen,th) and frictional (Sgen,f) components of irreversibility were reported in outputs. As Re increases, the residence time decreases and lower outlet temperature has been achieved. Sgen,th decreases about 57.36% with growth of Re while Sgen,f increases about 17.44 times. As the number of rows of tapes increases, the value of Sgen,f enhances about 69.23% while the value of Sgen,th decreases around 3.67%. Increase of pitch ratio causes Sgen,th to decrease about 11.25% while frictional component increases around 76.7%.
