Research on icing scaling law for rotating cone

In order to study the icing scaling theory of rotating cone, ignoring secondary factors, an icing scaling law suitable for rotating cone was established based on the law for static parts. Using the icing scaling law established in this paper, the error of droplet collection characteristics and ice shape were analyzed through the numerical simulation method. By this way, the reliability of this icing scaling law was estimated. Results show that when the rotating speed of the full size cone are 1000 r/min and 5000 r/min respectively, parameters deduced by the method in this paper was used for simulation. The errors of droplet collection characteristics and ice shapes in the same position of the full size and half scale size are 2.7% and 5.3% respectively, which indicates the method for choosing the scaling parameters is reliable and icing scaling law is effective. This law has certain reference value for studying the theory of icing wind tunnel and choosing parameters in the ice wind tunnel test.
