Our news journalists obtained a quote from the research, "Subsequently, the classical finite difference method is applied to determine the boundary conditions of the pipelines. In addition, the transfer matrix method is used to simulate the propagation process of the acoustic waves inside the pipelines. Finally, by conducting length-limited periodic drill string experiments, it is shown that this model and algorithm can be used to obtain the acoustic-wave spectrum distribution and impulse response characteristics inside periodic pipelines under operational conditions."
According to the news editors, the research concluded: "This method provides a theoretical basis for the fault diagnosis of acoustic-wave transmission systems for oil industry applications."
