Peristaltic transport of Johnson–Segalman fluid with homogeneous–heterogeneous reactions: a numerical analysis

The aim of present communication is to explore characteristics of radial magnetic field on the peristalsis of non-Newtonian material. Here Johnson–Segalman fluid model is used. The channel walls comprise the curvature effects. Mathematical description is formulated in view of mixed convection, Joule heating and heat generation effects. The boundaries of the curved channel satisfy the velocity slip and convective conditions. Additionally, the effects of homogeneous–heterogeneous reactions are also taken into account. Simplified form of the mathematical modelling is attained through low Reynolds number and large wave length deduction. The systems of nonlinear differential equations are solved numerically. The obtained numerical solutions for velocity, temperature and homogeneous–heterogeneous concentration are justified through graphical results.
