Abstract

A transient hot-wire technique was applied to examine the influence of the Coriolis effect on heat transfer on a centrifuge. A thermal conductivity measurement facility, once flown on board the TEXUS-24 rocket, was set on the 7.25 m rotating arm of the centrifuge. The temperature increase of the sensing wire, which was on a solid state substrate immersed in mercury, depended not only on input power and rotational acceleration but also on the orientation of the specimen. The temperature increase was affected by the Coriolis force, depending on the orientation: enhancement or suppression of heat transfer from the wire by convection.
