N2 - A numerical approach to improve prediction capability of transonic buffet onset based on URANS solutions is presented. In the computation of unsteady flowfield over NACA0012 wing section, numerical perturbation is artificially introduced to avoid convergence to a pseudo steady solution where buffet phenomenon is expected to take place. It is shown that the buffet onset can be easily determined from variation of RMS of unsteady flowfield. The computed boundary of buffet onset favorably agrees with the experimental data.
