The magnetohydrodynamics flow of a nanofluid over an exponentially curved stretching surface is deeply focused in the current study. By using the assumption on the curved stretching surface, the governing equations are established. We obtain nonlinear partial differential equations by utilizing the boundary layer estimation on the Navier–Stokes condition. These equations are converted into nondimensional system ordinary differential equations, using a suitable similarity transformation. The governing system of equations is tackled through an analytical method. The impacts of different pertinent parameters involved in the governing equations are illustrated graphically, whereas the numerical values of R e s 1 2C f ,R e s 1 2 S h s, and R e s 1 2 N u are also tabulated. The velocity profile declines with an increase in values of magnetic parameter and porosity parameter. The temperature profile is increasing, when the value of a thermophoretic parameter and Brownian motion parameter increases. A higher activation energy displays a stronger concentration profile. The concentration profile decreases for increasing values of the Schmidt number. The concentration profile shows the inverse impact for increasing values of the thermophoretic parameter and Brownian motion parameter. The focus of this study was to examine the heat transfer rate of nanoparticles.
