Duct sound propagation prediction based on grazing flow duct test

摘要

摘要: 通过平板声衬流管试验，测试了管道内无流动和有流动下不同入射声波频率的管道壁面复声压，并基于试验模型与数据分别开展了二维和三维管道声传播预测，将试验测量结果与预测结果进行了对比。结果表明：二维和三维的预测结果非常吻合，尤其是在无流动条件下；在不同流动条件和不同频率下，声传播预测给出了与试验数据较为吻合的结果，壁面声压级的趋势与试验结果一致，基本验证了管道声传播预测模型的准确性；对比不同流动条件和频率点，有流动下预测的壁面声压级的误差比无流动更大，低频下预测的壁面声压级的误差比高频更大。

Abstract: Acoustic complex pressure distribution on the duct wall opposite to the acoustic liner sample was obtained from grazing flow duct test with and without flow. Based on the test model and data, sound prediction study was carried out to validate the 2D and 3D duct sound propagation models. Result showed that 2D and 3D prediction results were very consistent, especially in the absence of flow. Duct sound propagation predictions were well matched to the corresponding grazing flow test results with and without flow at different frequencies, which verified the sound propagation model accuracy. Considering the influence of flow and frequency, the error between prediction and test results with flow was bigger than the situation without flow, and error at low frequency was bigger than that at high frequency.
