G050055 Icing Phenomena on Fan Blade Rotating in Freezing Fog : Anti-icing effect of surface properties of blade

Abstract

The purpose of this study is to understand the icing phenomenon on the fan blades in freezing fog, and to develop the anti-icing technology. The growth of icing on a blade was observed , and the mass of icing was measured on each blade with different surface properties , contact angle and surface roughness. As the results , the relations growth of icing and decrease of air flow rate were clarified , and it was found that high contact angle and low surface roughness had high effect for anti-icing.
