The Role of Propagation Characteristics in Acoustic Emission Pipeline Leak Location
Review of Progress in Quantitative Nondestructive Evaluation
INTRODUCTION The highly dispersive nature of fluid-filled pipeline systems makes the use of traditional time-of-flight source location techniques generally ineffective. Because such methods rely on the assumption of a non-dispersive signal, they do not compensate for the multimodal characteristics of a real acoustic signal. This paper describes on-going work at ISU to understand the underlying principles of multi-mode propagation in fluid-filled pipes and to develop leak location signaldoi:10.1007/978-1-4615-5339-7_65 fatcat:p4iddlkbe5frrlywwtkdobcbta
