Abstract “An Efficient Approach to Simulating Ice Accretion on 2D and 3D Airfoils”
Accurately predicting collection efficiency and ice accretion requires a tight coupling between the water/ice particle trajectories, the aerodynamics and the thermodynamics.
Being able to efficiently link the numerical simulation with the geometrical change that it implies can be a paramount.
A study was carried using a radial basis function approach within a detailed CFD analysis loop to demonstrate the ability to dynamically morph an aircraft wing profile to realistic ice shapes in both 2D and 3D.
Two 2D airfoils (NACA0012 and GLC305) and one extruded airfoil profile (based on NACA0012) were used and six complete ice shapes based on the LEWICE 2.0 validation manual were applied performing CFD simulations at clean,intermediate and complete accretion stages to investigate the effect on aerodynamic lift and drag.
