Euler solver with shock capturing
We use a high-order Euler solver to study aeroacoustic problems that have nonlinear physics. In the video, the Euler solver shows what happens when a turbulent field impinges on the leading edge of a transonic aerofoil. This kind of problem is relevant for aircraft engine components that operate at high speeds and that are subjected to oncoming flow disturbances. A shock-wave formed near the mid-chord of the aerofoil interacts strongly with the incoming turbulent field (shown in the bottom right corner of the video). The resulting noise radiated from the leading edge and the shock-wave is illustrated in the video. The solver employs high-order numerical schemes and non-reflective boundary conditions, together with a local artificial diffusivity model for the shock capturing.
