Prediction of broadband noise radiated from a cascade of real-airfoils interacting with turbulent gusts.

        <overlapping grids; background ; NACA0012>

<pressure perturbation>

                                                                <Acoustic power>

3rd CAA Benchmark Category4,

4th CAA Benchmark Category3, Problem2 "cascade-gust interaction"

- Pressure and velocity Contours (27 passages)-

         - Mean Pressure distribution on reference airfoil-

           -Comaprison of computed SPL[dB] on the suction side-
