Abstract: Innovative approach for simulation of nanoliquid natural convection through a permeable wavy space was scrutinized. Analysis has been conducted within inclined porous rectangular cavity having cold side borders under the impacts of heated internal wavy horizontal cylinder and uniform tilted magnetic field. The considered boundary-value problem devised on the basis of the Darcy linear law, Boussinesq relation, Rosseland approach and Lorentz force has been resolved by the finite volume technique. The impacts of nanomaterials’ shape, buoyancy force, radiation term and Hartmann number on nanoliquid hydrodynamic treatment have been investigated. Outcomes have proved that greater quantities of shape factor result in the greater convection. By enhancing magnetic forces, convection becomes weaker.
