Flow of magnetic shear thinning nano fluid under zero mass flux and hall current

In this research, the investigation of Hall and ion-slip effects on oblique stagnation point flow of magneto hydrodynamics Casson nanofluid have been discussed with Newtonian heating and zero heat and mass on an elastic surface. The mass concentration equation is also contemplated to examine the flow. By use of proper similarity transformation the governing equation of model are transformed into system of non-linear ODEs. The numerical results are presented by using the Runge-Kutta (RK) Fehlberg method, accompanied by the shooting technique by converting the system of ODEs to first-order ODEs. The effect of all physical constraints on velocity, temperature, and nanoparticles' concentration is shown graphically. Skin friction quantities, heat and mass flux are the physical quantities which are to be measured numerically. Temperature and concentration of nanoparticles near the wall in negligibly small for magnetic field parameter but this have a dominant influence on temperature and concentration of nanoparticles far away from the surface. Also it is observed that mass flux at the surface is larger for Ion slip parameter and Hall parameter, while skin friction coefficient at surface rises for magnetic field parameter but decreases for Hall parameter.
