Abstract: Current numerical simulation investigates the turbulent flow of nanomaterial and forced convection behavior within a solar system equipped with twisted tape. The top side of unit is under the impact of solar flux and the bottom side is isolated. Entropy generation (Sgen) of the tubular flows at Reynolds numbers ranging from 4000 to 20000 have examined for various cases with two geometric parameters namely; diameter ratio and number of revolution. Component of Sgen, Bejan number and entropy ratio are reported in outputs. Utilizing greater pumping power generates more disturbances in flow and Bejan number reduces. Sgen,f is directly proportional to diameter ratio because of more interaction of nanofluid
