In this work, effects of nonlinear thermal radiation and first order chemical reaction on the boundary layer flow of Williamson nanofluid over a non-uniformly thicked stretchable Riga plate are examined. The analysis is subjected to the newly devised zero nanoparticles mass flux surface conditions and heat transfer due to convective boundary conditions. Governing boundary layer equations depicting mechanical properties of the considered plate and flow over it are made dimensionless using suitable transformations. Numerical results obtained through an implicit finite difference scheme (Keller-box method) reveal that flow inside the boundary layer is substantially influenced by radiation, chemical reaction, and a surface parallel Lorentz force.
Nanofluid flow and heat transfer in a rotating system is studied numerically using fourth-order Runge–Kutta method. The important effects of Brownian motion and thermophoresis have been included in the model of nanofluid. The numerical investigation is carried out for different governing parameters namely: Reynolds number, Rotation parameter, injection parameter, Schmidt number, Thermophoretic parameter and Brownian parameter. The results indicate that skin friction parameter increases with augment of Reynolds number and Rotation parameter but it decreases with increase of injection parameter. Also it can be found that Nusselt number has a direct relationship with Reynolds number and injection parameter while it has a reverse relationship with Rotation parameter, Schmidt number, Thermophoretic parameter and Brownian parameter.
