In this work, the $\gamma$-$Re_{\theta}$ (LM) transition model has been implemented within the open-source CFD framework SU2. The model is based on two transport equations, one for intermittency and one for a transition onset criterion in terms of momentum-thickness Reynolds number. Transition-to-turbulence models coupling has been implemented for both the Spalart-Allmaras and the Menter SST models. The LM2015 variant has been implemented to assess the capability of predicting crossflow-induced transition on 3D test cases. Extensive validation has been performed on consolidated benchmarks on both 2D and 3D geometries. Numerical results are in good agreement on the whole range of test cases.
