This study experimentally demonstrates the coexistence and transition between weak and strong wave turbulence during the interaction of acoustic waves and turbulent flows. We identify conditions under which different wave turbulence regimes occur based on the wave number of the turbulent flow and acoustic waves. As the sound frequency increases, strong wave turbulence dominates, requiring a specific scaling factor to reconcile the spectra with the weak turbulence theory. Our analysis using the wave turbulence framework is confirmed by experimental results, providing deep insights into the complex interaction between acoustics and turbulence.

声学展宽中弱波湍流与强波湍流的共存与转变


这项研究通过实验证明了声波与湍流相互作用过程中弱波湍流和强波湍流的共存和过渡。我们根据湍流和声波的波数确定不同波湍流状态发生的条件。随着声音频率的增加，强波湍流占主导地位，需要特定的比例因子来使频谱与弱湍流理论相一致。我们使用波湍流框架的分析得到了实验结果的证实，为声学与湍流之间的复杂相互作用提供了深入的见解。
