Testing Messinger Freezing Fraction Correlations with the IceVal Database

"an empirical relationship was obtained which correlated ice accretion thickness and ice angles with theoretical impingement parameters." 1 Introduction Studies have correlated icing conditions to ice shapes and their effects. Here, we will test one using the 3332 experimental ice shapes cases in the IceVal database 1 without ice protection. The studies had well-planned series of test conditions for their objectives. However, when we use all 3332 IceVal experimental shapes from tests with diverse objectives, things can get messy. We will see that the final results are surprisingly good. NASA/CR-2005-213852 3 NASA/CR-2005-213852 "Evaluation and Validation of the Messinger Freezing Fraction" has been reviewed previously in Conclusions of the Ice Shapes and Their Effects thread. It looked at correlating ice shape parameters to calculated leading edge freezing fraction. The test cases within it are now a subset of the IceVal database. 40 condition were tested to verify an implementation …
