Abstract
An investigation is conducted to discern the effects of centrifugal and Coriolis forces on a rotating hot-wire. The probe is calibrated in a wind tunnel as well as in a rotating mode. The effect of rotation is found to be negligibly small. A small change in cold resistance (1.5%) is observed in the rotating wire. The rotation seems to have a negligible effect on the fluid mechanics, heat transfer and material characteristics of the wire. This is a significant conclusion in view of the potential application of the hot-wire probe in a rotating passage (such as turbomachinery).
