Simulation of nanoparticles second law treatment inside a solar collector considering turbulent flow

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 (S gen ) 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 S gen , Bejan number and entropy ratio are reported in outputs. Utilizing greater pumping power generates more disturbances in flow and Bejan number reduces. S gen,f is directly proportional to diameter ratio because of more interaction of nanofluid
