In this study, graphene nanoplatelet/platinum hybrid nanofluid with different volume fractions in 3-D triangular solar still has been simulated. The governing equations are formulated using the three-dimensional formula, and discretization is performed using the finite volume method. The volume fraction of nanofluids is set at 0, 0.05%, and 0.1%. Also, the Rayleigh number varies between 10(3) and 10(6). Among the items studied in this study is the Sherwood number to show the ratio of mass transfer through convection to mass permeability. In addition, the following variable that was studied in this work is the Nusselt number, that indicates the amount of heat transfer. This study showed that if nanofluids are used, the Sherwood number increases, compared to the normal state of pure water and the Nusselt number; adding nanoparticles to the base fluid causes significant growth. Also, in another part of this study, it was shown that if water cooling is used on glass, the efficiency will increase.
