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.
