Magnetothermal Rayleigh-Benard Convection of Paramagnetic Oxygen Gas in a Rotating Shallow Vertical Cylindrical Container

We carried out complete transient three-dimensional numerical computations to clarify the heat transfer rate characteristics of magnetothermal Rayleigh-Benard convection of paramagnetic oxygen gas in a rotating shallow vertical cylindrical container. When the container without rotation was fixed at the location where (gradB2)Z became minimum on the center line, the average Nusselt number of magnetothermal Rayleigh-Benard convection increased in comparison with that of Rayleigh-Benard convection. When the container with rotation was fixed at the same location, the average Nusselt number of rotating magnetothermal Rayleigh-Benard convection increased in comparison with that of magnetothermal Rayleigh-Benard convection for the specific rotational Reynolds number.
