Characteristic of thermal buoyancy and heat source on hybrid nanofluid stagnation-point flow under the action of convective boundary condition and induced magnetic field

An analysis is presented for the stagnation-point two-dimensional fluid flow of hybrid nanofluid towards an expanding surface characterized by the induced magnetic field. Further, the consideration of thermal buoyancy and additional heat source enhances the flow phenomena with various physical parameters involved in it. This work has significant novelty due to the behavior of the convective boundary conditions. Besides, due to the convective term the nonlinear differential equations designed in this problem are incorporated and are resolved numerically by executing the Runge-Kutta-Fehlberg method. The key resolution of this new paper is to examine the special effects of numerical variation in different parameters on the functions with the profiles of velocity, induced magnetic field profile, and energy of hybrid nano liquid. Additionally, three different classes of nanosized particle configurations named brick, cylinders, and platelets shapes are examined for the implementation of the Hamilton-Crosser thermal conductivity model. In the end, the influences characterizing the local Nusselt number and the coefficient of skin friction profiles have been discussed for unalike shapes of nanosized particles are discussed. In the above study, it is found that the platelet-shaped nanosized particle is more efficient in comparison to the other shapes considered herein. Further, particle concentration and particle shape are also favorable in enhancing fluid temperature in hybrid nanofluids in contrast to pure fluid.
