Radiative heat transfer study for flow of non-Newtonian nanofluid past a Riga plate with variable thickness

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.
