In this study, the flow and heat transfer components of convection are numerically investigated in a hybrid nanofluid-filled, porous-medium enclosure with wavy walls. The flow is considered to be buoyancy-driven under a constant inclined magnetic field and heat radiation (Rd). The cavity is partially heated from its left wall and is cooled by its wave-like right wall while the other walls are adiabatic. To express the results, streamlines, isothermal, and the Nu are used. Analysis is done to determine how heat transfer is affected by thermal radiation (Rd), the Hartmann number Ha, the inclined magnetic field, the left heater’s dimensionless location (D), the heat source’s dimensionless length (B), and the hybrid nanofluid’s volume fraction. The average Nusselt number is increased when the volume friction of hybrid nanofluids increases. Additionally, as the dimensionless heat source length B rises, the rate of heat …
