Proposed inflow/outflow boundary condition for direct computation of aerodynamic sound

摘要

Recent studies of aerodynamic sound generation and radi- ation are relying more frequently on computer simulations. Direct simultaneous computation of the flowfield and the radiated Sound offers the most detailed description of aerodynamic sound Generation processes. A primary difficulty in the development of Computational techniques for direct aeroacoustic computation has Been the inadequacy of numerical boundary conditions.
