Heat transfer analysis of MHD rotating flow of Fe3O4 nanoparticles through a stretchable surface

The flow of a magnetite-H2O nanofluid has been considered among two rotating surfaces, assuming porosity in the upper plate. Furthermore, the lower surface is considered to move with variable speed to induce the forced convection. Centripetal as well as Coriolis forces impacting on the rotating fluid are likewise taken into account. Adequate conversions are employed for the transformation of the governing partial-differential equations into a group of non-dimensional ordinary-differential formulas. Numerical solution of the converted expressions is gained by means of the shooting technique. It is theoretically found that the nanofluid has less skin friction and advanced heat transport rate when compared with the base fluid. The effect of rotation causes the drag force to elevate and reduces the heat transport rate. Streamlines are portrayed to reveal the impact of injection/suction.

Automated summary

The study investigates the flow of a magnetite-H2O nanofluid between two rotating surfaces, considering its impact on skin friction and heat transport rate. The results show that the nanofluid has lower skin friction and higher heat transport rate compared to the base fluid, but rotation effect increases drag force and reduces heat transport rate.
