The existing article explores the attributes of convection and Joule heating across a magnetohydrodynamics two-dimensional stagnation point flow of a nano liquid depending on the permeable curved stretching/shrinking surface and mass suction. Applying the non-dimensional variables, the basic model of partial differential equations (PDEs) is converted to the dimensionless ordinary differential equations (ODEs), which are solved through the bvp4c method (bult-in function in MATLAB). Multiple graphical results have been examined to observe the effect of diverse flow parameters against temperature, friction drag, velocity and heat transfer. From these results, it has been determined that the temperature profile escalates with the escalation of Hartmann, Eckert and Biot number, nanoparticles concentration and curvature parameter, although the velocity of fluid reduces with escalating values of nanoparticle concentration parameter, curvature parameter, and Hartmann number. It is equally important to indicate that the friction drag reduces with large curvature and rises with greater suction however the rate of heat transfer declines with least value of Eckert number and improves with strong suction, Hartmann, and Biot number.
