Abstract

This article presents a novel approach to include turbulent wedges in local correlation-based \gamma transition models. The turbulent wedge is modeled by increasing the intermittency at the wedge apex. The wedge develops downstream without further interference in the transition model behavior. The method is demonstrated for an experimental high Reynolds number test case on the NASA CRM-NLF configuration. Wedges are successfully created, but the wedge angles are too large compared to the experimental data. Grid spacing, initial disturbance size, and scaling of the diffusion term only have a minor effect on the wedge angles.
