Abstract This research deals with the analysis of magnetizable hybrid nanofluid of MWCNT-Fe3O4/H2O inside a circular cavity with two circular heaters. A wire carrying electrical current has been located in the center of each heater. The magnetic fields strengths created by the wires carrying electrical current are not the same. The governing parameters studied includes Rayleigh number (Ra = 104 to 106), location angle of heaters α = 0–π/2, the magnetic strengths ratio parameter γr = 0.2–5, magnetic number Mnf = 0–1000, Hartmann number Ha = 0–50, nanocomposite particles concentration φ = 0–0.3%. Results demonstrate that dispersing the hybrid nanoparticles of MWCNT-Fe3O4 inside the host fluid augments the convective heat transfer.
