Predicting buffet over an airfoil is one of the challenging problems for current CFD because the phenomenon is complex and unsteady. In this paper, we conduct a simulation of the transonic buffet over a super-critical airfoil using FaSTAR code which is the unstructured CFD code developed by JAXA. Zonal DES approach is employed for the flow simulations, which is RANS/LES hybrid approach. Results are compared with the past research and the experimental data.
