説明
With the aim of correctly estimating AE source locations in liquid-storage tanks, propagation behavior of AEs in water-loaded semi-spherical and cylindrical tanks were studied. Pressure profile or radiation pattern for semi-spherical tank indicated a complex profile with peak pressures and dead angles depending on both the source frequency and size. Experimental profile suggested the mode-converted P-wave in water to and from the Lamb wave (Ao-Lamb at 3000m⁄s) . Features of the radiation pattern agreed well with AE-peak profile measured for water-loaded cylindrical tank. The Lamb wave via bottom plate were converted to the large P-wave in water at the radiation angle of 30°. AEs with their sources on the bottom plate were found to arrive the AEs ensors on shell wall in the sequence of 1) Lamb wave with small amplitude, 2) Mode-converted P-wave with large amplitude, 3) direct P-wave in water. Source location method and accuracy of AEs were also discussed in relation to the propagating paths of AEs.
