Large-Eddy Simulation of Droplet Impingement Using a Lagrangian Particle Model

Modeling of icing is important for the design of aircraft lifting surfaces and for the design of efficient propulsion systems. The computational modeling of ice accretion prediction is important to replace the expensive experimental techniques for calculating the ice shapes in Icing tunnels, and the first step toward modeling ice accretion is to accurately compute the droplet collection efficiency which acts as the input to the accretion model. In this work, the authors perform large-eddy simulations of supercooled droplet transport and impingement onto complex aircraft geometries using a Lagrangian particle approach. The authors assess the improvement in modeling droplet impingement by computing the droplet collection efficiency and by comparing with the existing experimental data.
