Large-scale swept-wing ice accretion modeling in the NASA Glenn Icing Research Tunnel using LEWICE3D
The study of aircraft icing is necessary to ensure the safety of commercial, military, and general aviation aircraft. The certification of modern commercial transports requires manufacturers to demonstrate that these aircraft can safely operate during icing conditions consistent with the standards …

Convection from ice roughness surfaces using scaled Reynolds numbers for larger NACA 0012 airfoils.
… of a larger NACA 0012 airfoil by increasing wind tunnel velocity and thus scaling the Reynolds number. This scaling is appropriate based on previous studies performed in the Icing Research Tunnel (IRT) at the NASA Glenn Research Center that determined relative roughness in the collection region of …

Simulations of droplet dispersion in the wakes of cylinders and icing tunnel spray bars
… behind cylinder wakes and downstream of icing tunnel spray bars were conducted. In both cases, a range of droplet sizes were investigated numerically with a Lagrangian particle trajectory approach while the turbulent air flow was investigated with a hybrid Reynolds-Averaged …

Hybrid Airfoil Design Methods for Full-Scale Ice Accretion Simulation
… from each method are validated using wind-tunnel test data. The thesis demonstrates the capabilities of each method with the help of specific design examples highlighting their application potential. In particular, the flap-system based hybrid airfoil design method is used to demonstrate …

Use of hybrid airfoil design in icing wind tunnel tests of large scale swept wings
… of commercial airliners for flight into known icing is difficult due to the expense and challenge in finding the desired icing conditions in flight. The large size of commercial aircraft relative to existing icing wind tunnels and lack of robust scaling methods also makes ice accretion wind …

Design of 3D swept wing hybrid models for icing wind tunnel tests
The study of aircraft icing is critical to ensure the safety of any aircraft that might experience icing conditions in flight, including general, commercial, and military aviation. The certification of modern commercial transports requires manufacturers to demonstrate that these aircraft can safely …
