NettetA linearized Euler equation (LEE) solver with an inflow boundary condition is used to generate single-frequency hydrodynamic instability … NettetIn this thesis an aeroacoustic method based on the linearized Euler equations (LEE) has been implemented in OpenFOAM. Instead of using the standard available OpenFOAM schemes, a different numerical method was implemented. This involves solving a Riemann problem to determine the convective terms.
