dc.description.abstractIce 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 real ice roughness surface. The current study characterizes the convective heat transfer of four ice roughness surfaces exposed to accelerating flow similar to that experienced by NACA 0012 airfoil and flow with negligible acceleration. The velocity boundary layer development along these surfaces was characterized as well. Each of the roughness surfaces was exposed to similar supercooled cloud conditions for different lengths of time to observe the changes in convective heat transfer with increasing accumulation parameter. The ice surfaces for this study were created from geometrically unwrapped laser scans of ice accretions to form a flat plate representation of the airfoil surface roughness.
