Objective of the present work is to explore the fluidity and thermal performance of Silver and Magnesium oxide mixed water based hybrid nanofluid over the penetrable hollow ampoule under the magnetic influence. Effective thermophysical modelling has been adopted along with the Darcy Forchheimer model engaged exclusively for the inertia of the porosity layer. Governing model equations were solved with the efficient Galerkin Finite Element Analysis (GFEM) and the outcomes were scrutinized towards the error tolerance of 10−6. Parametrical study has been performed with crucial and influencing constraints to traces the behaviors of streamlines and isotherms. Added to the flow influencing constraints the meandering structure of the enclosure itself creates a significant impact on the fluidity which can be evident through the contours developed in the streamline plots. Initial values of the Rayleigh number (Ra) and the Darcy number (Da) make the thermal dissemination stays away from the walls particularly in the hooter wall side with two cliff bar structures. Thermal transference rates get notable assistance from most of the constraints except from the accumulative Hartmann number (Ha) and for the lower Rayleigh number (Ra).
