Numerical Code Validations and Quantitative Analyses of Ice Accretion Shapes

Quantitativeanalyses of ice accretion shapes have not been sufficiently investigated in previous researches; consequently, there are limitations to judge the accuracy of numerical codes and to analyze the change of ice accretion shapes in various icing conditions. In this study, the developed code has been quantitatively validated with available experiments and the other numerical codes on the cylinder and the airfoil. Maximum thickness, its heading direction and ice accretion area are quantified and expressed in the polar coordinate system for the comparison with other numerical results of NASA, ONERA and DRA, The comparison among the present code and the other codes yields sufficiently accurate results for the analyses of ice accumulated shapes with various icing conditions. It was found that discrepancy of ice shapes around the cylinder turns out to be greater than those of the airfoil, which is due to the incapability of the present code to capture the massive separation. However, the present code yields the highly reliable and consistent results for the airfoil shapes.
