Estimating acoustic wave dispersion in pipelines filled with water is studied using theoretical analysis and laboratory experiments. Previous methods for experimentally estimating the dispersion of the propagating modes require multiple spatial measurements, making it difficult to measure. In this work the authors propose a method that utilizes only one spatial measurement using a singular value decomposition based approach. Experimental results of a cylindrical high-density polyethylene pipeline are used to demonstrate the usefulness of the approach. The approach could be useful in estimating the size and material properties of pipelines.

使用单个空间测量值估算输水管道中的声波色散。

利用理论分析和实验室实验研究了在充满水的管道中估计声波色散的方法。实验上估计传播模式离散的先前方法需要多次空间测量，因此很难测量。在这项工作中，作者提出了一种方法，该方法仅使用一种基于奇异值分解的方法进行空间测量。圆柱形高密度聚乙烯管道的实验结果用于证明该方法的有效性。该方法可能有助于估计管道的尺寸和材料特性。
