A variant of the local correlation-based transition model (LCTM) ? is presented to account for prediction due stationary crossflow instabilities. The Tc1 criterion a approximation well-known C1 by Arnal (1984), evaluated locally through auxiliary functions expressed solution Falkner–Skan–Cooke (FSC) equations. criterion, originally proposed Menter and Smirnov (2014), uses wall-normal directional change normalized vorticity as indicator strength. Hereafter, an original calibration FSC-based & proposed. sweep angle included in order achieve better results on non-wing-like geometries. capability this predict therefore discussed. validation study using experimental data 6:1 prolate spheroid sickle wing.
