MHD Mixed Convection of Hybrid Ferrofluid Flow over an Exponentially Stretching/Shrinking Surface with Heat Source/Sink and Velocity Slip

This paper investigates the mixed convection flow related to Fe3O4-CoFe2O4/water hybrid ferrofluids on stagnation point over an exponentially stretching/shrinking surface with influence of magnetohydrodynamic (MHD), velocity slip, and heat source/sink. The proposed system differential equations is reduced using similarity transformation procedure that numerically solvable MATLAB. Dual solutions are obtained for various governing parameters, in which first solution found be a stable state via stability analysis. CoFe2O4 nanoparticles volume fraction increases transfer rate skin friction coefficient while delaying separation boundary layer at bifurcation point. Adding gives better than ferrofluids. presence magnetic field enhances fluid velocity. increased strengths sink stretching parameters give results transfer, reversed source shrinking parameters. slip does flow.
