Numerical Analysis of Ice Accretion and Icing Effects on Airfoils

Abstract:

Aircraft icing cause significant degradation in aerodynamics performance and flight safety. Numerical methods are developed and presented to simulate two icing-related problems for airfoils, namely ice accretion and icing effects. Ice accretion on the leading edge of the NACA 0012 airfoil is predicted using CFD method based on spring analogy. A four-order Runge-Kutta method is used to solve the droplet trajectory equation. Besides, we use the integral form of Navier-Stokes equations and the Spalart-Allmaras turbulence model to study the icing effects. Designing three different icing models, the flow fields are analyzed. The results are in good agreement with the experimental data and show preliminarily that numerical method is feasible and effective.
