Rheological properties of Darcy–Forchheimer hybrid nanofluid flow with thermal emission and heat source over a curved slippery surface

The Darcy–Forchheimer's flow of hybrid nanofluid (HNF) over an extending curved slippery surface is described in this paper. The Darcy–Forchheimer influence designates the viscous fluid flow in a porous medium in the presence of nonlinear thermal radiation, magnetic strength and suction/injection. To make the hybrid nanofluids, magnesium-oxide (MgO) and Ag (silver) nanoparticles (NPs) are saturated in water. The principal equations are rearranged to non-dimensional ODEs using similarity substitution. To resolve the numerical arrangement of modeled equations, the ^parametric continuation method is used. The effect of flow variables on energy, mass and velocity profiles is discussed. The result shows that when the curvature component is taken into account, the energy is lowered, but the velocity field is elevated. Thermal Biot number intensifies heat transport, and the rate of escalation is faster in hybrid nanosuspension. For increased nanoparticle content, energy and velocity profiles are increased. (author)
