A machine learning study of wind-driven runback/flow-off multiphase flows pertinent to aircraft icing phenomena
In-flight icing and ground icing are widely recognized hazards that have a substantial impact on the safety of aircraft during the processes of takeoff, cruising, and landing in cold weather conditions. The unsteady runback behavior of wind-driven runback water film (WDRWF) flows over aircraft …

Validation of 3-D ice accretion documentation and replication method including pressure-sensitive paint
… is important to the study and understanding of aircraft icing. For research and certification purposes, replicas of ice accretions generated from icing wind tunnels are fabricated to perform aerodynamic tests in dry-air wind tunnels. The currently employed replication method consists of creating …

Lagrangian Parcel Volume method applied to icing surfaces to predict impact efficiency
… to predict how and where ice will accrete on an aircraft, engineers first need to be able to track the path and concentration of water particles; this will allow for a better representation of water impingement and ice accretion. This tracking can be accomplished by using either a Lagrangian …
