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.
