摘要

The present exploration aims to deliberate silver-water nanofluid flow with homogeneous- heterogeneous reactions and magnetic field impacts past a nonlinear stretched cylinder. The novelty of the presented work is enhanced with the addition of Newtonian heating, heat generation/absorption, viscous dissipation, nonlinear thermal radiation and joule heating effects. The numerical solution is established via Shooting technique for the system of ordinary differential equations with high nonlinearity. The influences of miscellaneous parameters including nanoparticles volume fraction (0.0 <= phi <= 0.3), magnetic parameter (1.0 <= M <= 4.0), nonlinearity exponent (1.0 <= n <= 5.0), curvature parameter (0.0 <= gamma <= 0.4), conjugate parameter (0.4 <= lambda <= 0.7), heat generation/absorption parameter (0.2 <= E-c <= 0.8), radiation parameter (0.7 <= K* <= 1.0), Eckert number (0.1 <= E-c <= 0.7), strength of homogeneous reaction (0.1 <= kappa(1 )<= 1.8), strength of heterogeneous reaction (0.1 <= kappa(2) <= 1.8) and Schmidt number (3.0 <= S-c <= 4.5) on axial velocity, temperature profile, local Nusselt number, and skin friction coefficient are discussed via graphical illustrations and numerically erected tabulated values. It is examined that the velocity field diminishes while the temperature profile enhances for mounting values of the magnetic parameter. An excellent concurrence is achieved when our obtained numerical calculations are compared with an already published paper in limiting case; hence dependable results are being presented.
