Abstract :In this research, heat transfer of nanofluid flow in a two-phase revolving system considering the magnetic field is investigated. The fundamental partial differential equations of momentum, mass, and energy reduced to the nonlinear ordinary differential equations which are solved using Akbari-Ganji’s Method insert ignore into journalissuearticles values(AGM);. The introduced method solves problems based on the Trial Function. The comparison between the numerical insert ignore into journalissuearticles values(Runge-Kutta Fourth-Order Method); and analytical results indicates great agreement in solving the nonlinear differential equations. Also, the impact of Schmidt insert ignore into journalissuearticles values(Sc); number and parameters such as Brownian insert ignore into journalissuearticles values(Nb); parameter, Magnetic parameter insert ignore into journalissuearticles values(M);, Melting parameter insert ignore into journalissuearticles values(δ);, Viscosity parameter insert ignore into journalissuearticles values(R);, Rotating parameter insert ignore into journalissuearticles values(Kr);, and Thermophoretic insert ignore into journalissuearticles values(Nt); parameter on the profiles of velocity insert ignore into journalissuearticles values(ginsert ignore into journalissuearticles values(η);, f`insert ignore into journalissuearticles values(η);, finsert ignore into journalissuearticles values(η););, temperature insert ignore into journalissuearticles values(θ);, concentration insert ignore into journalissuearticles values(ϕ);, Nusselt number insert ignore into journalissuearticles values(Nu);, and surface friction coefficient insert ignore into journalissuearticles values(Cf); are studied. Conclusions show that by the increase in Viscosity parameter, the temperature profile increases in the range of [0, 1], but with the increase in Melting parameter, temperature profile decreases. In addition, by increasing Rotating parameter or decreasing Brownian parameter, the surface friction coefficient profile increases from top to bottom plate. Furthermore, the results show that nanofluid heat transfer rate in a two-phase revolving system can be improved by controlling the magnetic field.
