N2 - This paper presents the extension of the open source Stanford University Unstructured (SU2) software suite to perform transition prediction simulations, which are caused by either Tollmien-Schlichting streamwise instability or crossflow instability. The integrated equations, γ-Reθt model and γ-Reθt-CF model, solving computational fluid dynamics analysis are coupled with Spalart-Allmaras turbulence model. In order to validate and assess the accuracy of the model in predicting the boundary layer transition, a series of transition flows are simulated including S809 airfoil, 30P30N multi-element airfoil and 6:1 prolate spheroid standard model. The results show the modified SU2 suite can predict transition accurately in various flow conditions such as natural transition and crossflow transition. The capacity and accuracy of the SU2 software suite in the numerical simulation can be greatly enhanced.
