Thermal-natural convection and entropy production behavior of hybrid nanoliquid flow under the effects of magnetic field through a porous wavy cavity embodies three circular cylinders

In this numerical contribution, hybrid nanofluid flow behavior, thermal characteristics, and entropy generation analysis through a porous enclosure containing three circular cylinders with magnetic field effects were investigated using finite element approach. The are arranged in horizontal arrangement the middle of cavity height, active hot central cylinder can move along vertical axis while other cold considered fixed. enclosed by an adiabatic wavy loaded Cu-Al2O3-water. results discussed for scrutinized parameters e.g., Rayleigh number (Ra), Darcy (Da), Hartmann (Ha), relative position (?), concentration volume nanoparticles (?). It was inferred that thermal-natural convective overall heat transmission reinforced boosting Ra Da, lowering Ha. Changing has remarkable effect on nanoliquid patterns, transfer characteristics.
