The indirect boundary‐element analysis is employed for developing a computational pass‐by noise simulation capability. An acoustic field reconstruction process is developed in order to generate the definition of the main pass‐by noise sources in a computational model. Numerical boundary‐element models that characterize the individual sources are combined in order to develop a system model for the pass‐by noise simulation. The acoustic field reconstruction process is validated initially by employing analytical solutions. The numerical techniques are also validated through comparison between numerical results and test data for component‐level and system‐level analyses. Specially, the source definition capability is validated by comparing the actual and the computationally reconstructed acoustic field for an engine intake manifold. The overall pass‐by noise simulation capability is validated by computing the maximum overall sound‐pressure level for a vehicle under two different driving conditions. [Research ...
