摘要

In the present work the extension of a recently published transition modeling approach is proposed. In the modified variant of the approach compressibility effects up to a Mach number of 1.6 are taken into account using the compressible formulation of the AHD transition criterion. Moreover, the Gleyzes criterion for the estimation of the transition onset location inside laminar separation bubbles was incorporated into the approach providing a higher accuracy for separation-induced transition points. The extensions were validated calculating the flat plate, the CAST10-2 airfoil and the Eppler 387 airfoil including grid resolution studies. Moreover, details with regard to the implementation and application of the extensions are given.
