Abstract
The flow due to stretching sheet has key role in many engineering fields such as making rubber sheets and plastic, wire drawing, glass-fiber manufacture and hot rolling etc. The Sisko fluid has its significant role in drilling fluids, blood, cement slurry, liquid polymers, paint and mud, synovial fluid and water-borne coating. Here, we examined the magnetic Sisko fluid flow via stretching sheet with convective conditions using Buongiorno’s model and flow problem occurring due to homogeneous–heterogeneous reactions. Influence of pertinent flow parameters viz. magnetic field, material index, Brownian motion parameter, thermophoresis parameter, Brownian diffusivity, Lewis number, ratio of diffusion coefficient, strength of homogeneous reaction, strength of heterogeneous reaction and Biot number are revealed by graphs for both shear thinning ( n < 1) and shear thickening ( n > 1) cases. The existing model has considered the case of unequal diffusion coefficients of chemical species. Hence, accounting the interaction of both homogeneous–heterogeneous reactions. One of the important outcomes of this work is concentration of auto-catalyst of Sisko fluid decreased due to rise in material index parameter.
