基于Khokhlov-Zabolotkaya-Kuznetsov(KZK)方程,在频域建立了求解三维非轴对称声场的方法,理论及实验研究了声波通过肋骨条状障碍物后的非线性声场分布,数值计算与实验结果相符。本文还讨论了条状障碍物对空间平均-时间平均声强(ISATA)的影响.
Based on the Khokhlov-Zabolotkaya-Kuznetsov (KZK) equation, a method of solving three-dimensional non-axisymmetric sound field is established in the frequency domain. The nonlinear acoustic field distribution of the sound wave passing through the ribs is studied theoretically and experimentally. The numerical calculation is consistent with the experimental results . The article also discusses the effect of stripe obstacles on the space-time-averaged sound intensity (ISATA).
