Heat and Mass Transfer Assessment of Magnetic Hybrid Nanofluid Flow via Bidirectional Porous Surface with Volumetric Heat Generation

Abstract

The theme of this article is to assess the impact of MHD flow of SWCNT + Ag + H2O hybrid nanofluid via a bidirectional porous stretchable sheet having volumetric heat generation and chemical reaction of higher order. The governing equations of the flow problem for working fluid are tackled by with RKF-4th and 5th order technique. The features of heat transfer, mass diffusion and fluid flow are depicted in the range of power law index number, $$1 \le n \le 6$$ ; Hartmann number, $$0.1 \le Ha \le 0.6$$ ; internal heat generation, $$0.1 \le H \le 2.2$$ ; chemical reaction, $$0.5 \le \Omega \le 4$$ ; chemical reaction order ( $$1 \le q \le 9$$ ) and nanoparticles volume fractions varies from 2 to 10%, and remaining parameters are fixed. The upshots of the current problem illustrate that with increase in volume fraction of hybrid nanofluid, thermal field function increases, while both velocity functions declined. Moreover, Nusselt number function is reduced with increase in volumetric heat generation and increases with order of chemical reaction for $$n = 1$$ and $$n = 2$$ .
