Boundary layer stagnation point flow of the Casson hybrid nanofluid over an unsteady stretching surface

This work examines the behavior of hybrid nanofluid flow toward a stagnation point on a stretching surface. Copper and aluminum are considered as the hybrid nanoparticles. The Casson (non-Newtonian) fluid model is considered for hybrid nanofluids applying magnetic effects perpendicular to the surface. The governing equations are reduced to the ordinary differential equations using similarity transformations. The resulting equations are programmed in the Mathematica software using the OHAM-BVPh 2.0 package. The most important results of this investigation are the effects of different physical parameters such as β, M, S, and Pr on the velocity profile, temperature profile, skin friction coefficient, and local Nusselt number. With the escalation of the magnitude of the Prandtl number Pr, the temperature profile slashes down, while with the variation of the Eckert number, the temperature field improves. The key outcomes specify that the hybrid Casson nanofluid has a larger thermal conductivity when equated with traditional fluids. Therefore, the hybrid fluid plays an important role in the enhancement of the heat phenomena. The ratification of our findings is also addressed via tables and attained noteworthy results.
