Abstract:
A rotating icing scaling law used for parameter selection for tests in an icing wind tunnel is established using the basic physical process of icing. The method of selecting parameters for a scale model of rotating components is also discussed. A dimensionless quantity, called the rotation number, is derived from the water film momentum equation in the rotating coordinate system. This parameter must be matched between the reference and the scale model. Water collection properties and ice accretion are numerical calculated through the similarity law established in this study to evaluate the effectiveness of the rotating icing similarity law. Results show that when the rotating speed of the full size cone is 1000 or 3000 r/min, nearly identical droplets collection features and ice shape can be obtained for the half scale model. Thus, the established rotating icing similarity law is effective and can be used as the theoretical guidance for parameter selection for ice wind tunnel tests.

Key words:  Ice shape, rotating icing scaling law, rotation number, water collection property, , ,
