Computation of Fe3O4-CoFe2O4 hybrid nanofluid flow in stretchable (Shrinkable) wedge with Variant magnetized force and heat generation

The use of a hybrid nanofluid, a relatively new invention in the field of nanofluids, results in better heat transmission. In the ongoing investigation, a hybrid nanofluid stagnation point flow involving Fe3O4-CoFe2O4 nanoparticles is utilized. To ensure novelty, the study incorporates reliable thermal properties on a stretching (or shrinking) wedge with variable magnetic fields and heat production, aiming to explore unique features of heat transfer. A set of relevant similarity transformation is utilized to generate ordinary differential equations and further solved numerically to obtain simulation results. The transformed dimensionless equations tackled numerically adopting the bvp5c MATLAB tool. Influence of several pertinent parameters on velocity and thermal distributions is analysed graphically. Surface plot and streamlines is presented for volume fraction and stretching/shrinking effects. It has been shown that magnetic field inclined the flow velocity across the domain due to sheet flow velocity. The wedge term boosted the velocity field, but the temperature distribution is decreased. The internal heating of the energy equation is influenced strongly by the entrenched thermofluidic terms. Computed numerical values are presented as a table for drag force coefficient and rate of heat transfer.
