Convection from manufactured ice roughness with varying flux boundary conditions.
… accidents. To predict the shape of these ice accretions, codes, such as the NASA LEWICE code, have been created that step through time and solve an energy balance for an iced airfoil. A critical part of this energy balance is convection over the initial ice roughness. However, determining …

Convection from laser-scanned ice roughness at multiple accretion vent times.
Ice accretions degrade aircraft flight safety and performance by decreasing the lift and stall angle, increasing the drag, and increasing the aircraft weight. A recent study found that the commonly used realistic ice roughness models did not replicate the convective heat transfer results of one …

Convection from ice roughness surfaces using scaled Reynolds numbers for larger NACA 0012 airfoils.
Ice accretions that develop on aircraft surfaces during flight adversely impact performance by increasing weight and drag, while also decreasing lift and stall margin. Previous studies at Baylor University characterized the convective heat transfer for roughness surfaces exposed to accelerating …

Experimental Study of Full-Scale Iced -Airfoil Aerodynamic Performance Using Sub-Scale Simulations
Determining the aerodynamic effects of ice accretion on aircraft surfaces is an important step in aircraft design and certification. The goal of this work was to develop a complete sub-scale wind tunnel simulation methodology based on knowledge of the detailed iced-airfoil flowfield that allows the …
