Evaluation of Boundary Conditions for Computational Aeroacoustics

摘要

The performance of three boundary conditions for aeroacoustics were investigated,namely, (1) Giles-1990; (2) Tam and Webb-1993, and (3) Thompson-1987. For each boundary condition, various implementations were tested to study the sensitivity of their performance to the implementation procedure. Details of all implementations are given. Results are shown for the acoustic field of a monopole in a uniform freestream.
