Swirl anti-icing is a promising aero-engine nacelle protection method. This study develops practical heat transfer calculation methods for jet entrainment and wall heat transfer. Sonic and subsonic jet expansion and mixing are analyzed to summarize entrainment laws. Spatially distributed heat transfer correlations are formulated for both swirling and jet impingement regions.
