The effects of the Coriolis force on a flow field, and on temperature increase during transient hot-wire heating, were studied by three-dimensional and time-dependent calculation as compared to the experimental result. We have found that the Coriolis force drastically changes the flow field as well as the heat transfer tendencies of mercury on a centrifuge. The origin of these changes is that the Coriolis force reduces the component of velocity parallel to the effective gravity, and increases the radial and azimuthal components normal to the direction of the effective gravity on the centrifuge. The order of the effect of the Coriolis force depends on the configuration and the characteristic length of the specimen.
