Calibrating the γ-Reθ Transition Model for Commercial CFD
Printer-friendly versionPDF version

The γ-Reθ transition model is the first correlation-based model designed for unstructured, parallel CFD codes. Two out of the three correlations required to complete the model have not yet been published by the originators of the model. This paper presents plausible forms for the missing correlation functions and describes a process for calibrating them against published data. The complete model and its implementation in a modern commercial CFD code is described. Results are presented for flat plate boundary layers, with and without pressure gradient, and for several airfoil and turbomachinery flows. A 3D multi-element airfoil simulation is presented as a case study of an industrial application.
