New publication: Prediction of Crossflow Transition using γ Transition Model Coupled with Reynolds Stress Transport Turbulence Model

We are thrilled to announce a brand-new paper in the OpenFOAM Journal

Pisharoti, N., and Brizzolara, S. (2025). Prediction of Crossflow Transition using γ Transition Model Coupled with Reynolds Stress Transport Turbulence Model. OpenFOAM Journal, 5, 131-147.

This research tackles the complex challenge of predicting laminar-turbulent transition in 3D boundary layers.

• The paper presents an enhanced SSG/LRR-ω-γ transition model. A novel local helicity-based criterion is introduced to accurately account for crossflow-induced instabilities, a critical phenomenon in aerodynamics.
• The improved model is put to the test against two challenging aerodynamic benchmarks: the NLF(2)-0415 infinite swept wing and the DLR 6:1 prolate spheroid.
• Results demonstrate that the new crossflow model accurately captures transition and shows improved agreement with experimental data compared to its original formulation.
• In the spirit of Open Science, the full source code and case files for this study are available for download directly from the article page, enabling you to build upon this work.
