  • The gust-cascade interaction noise was numerically simulated using computational aeroacoustics by solving the two-dimensional linearized Euler equations.In order to minimize the dispersion and dissipation errors,the dispersion-relation-preserving scheme was applied to perform the spatial discretion and the optimized 4/6 low-dissipation and low-dispersion Runge-Kutta scheme was used for the time integration.Appropriate boundary conditions were prescribed or established for various boundaries.The non-reflecting boundary conditions were firstly validated by simulating gust convection in the free space.Then the interaction noise due to the gust/flat-plate cascade was simulated.The numerical results agree well with exact solutions.Finally the numerical results of the noise from the gust/cascade(with NACA-0012 airfoil) interaction are presented which demonstrates the feasibility of the numerical procedure.
