The present study concerns the modelization and numerical simulation for the heat and flow exchange characteristics in a novel configuration saturated with a non- Newtonian Ag-MgO hybrid nanofluid. The wavy shaped enclosure is equipped with one- quarter of a conducting solid cylinder. The system of equations resulting from the math- ematical modeling of the physical problem in its dimensionless form is discretized via the higher-order Galerkin-based finite element method (GFEM). The dependency of various factors and their interrelationships affecting the hydro-thermal behavior and heat ex- change rate are delineated. The numerical experiments reveal that the best heat transfer rate is achieved for the pseudo-plastic hybrid nanoliquid with high Rayleigh number and thermal conductivity ratio and low Hartmann number. Besides, the power-law index has a major effect in deteriorating the heat convection at high Rayleigh number.
