Abstract
Ice accretion in the form of glaze on rotor blades was investigated experimentally with a commercially available axial fan. In the experiments, fine water droplets generated by a spray nozzle were drawn into the axial fan in a low temperature room. Observations of ice shape and mass measurements of the ice were carried out to understand fundamental features of the glaze on the rotor blades. From the observations, we found characteristic shapes of the glaze near the leading edge of the fan blades which was caused by runback ice accretion influenced by the centrifugal force.
