Propagation characteristics of low-frequency axisymmetric waves in fluid-filled pipes embedded in the viscoelastic medium
《Chinese Journal of Acoustics》2022年第3期221-237,共17页QIAN Jiawen HAN Qingbang SU Nana BAI Le QIAN Xintong 
supported by the National Natural Science Foundation of China(12174085);the State Key Laboratory of Acoustics,Chinese Academy of Sciences(SKLA201913)。
The propagation characteristics of the low-frequency axisymmetric waves in buried fluid-filled pipes are investigated theoretically,based on the Kennard thin-walled shell equations,the Helmholtz equation,and the Kelvi...

Excitation and propagation of axisymmetric longitudinal guided waves in pipes immersed in infinite liquid media
《Chinese Journal of Acoustics》2010年第4期346-358,共13页LIU Shengxing 
the National Natural Science Foundation of China(10704064,40776022);the Natural Science Foundation of Fujian Province,China(D0810027)
The transient elastodynamic responses of the vacuum-filled and liquid-filled pipes surrounded by infinite liquid to external axisymmetric forces are simulated by employing the acoustic-structural coupled finite elemen...
Study on resonance frequency of thermoacoustic resonance pipes被引量：1
《Chinese Journal of Acoustics》2005年第1期52-62,共11页FANLi WANGBenren JINTao ZHANGShuyi 
This work was supported by the National Natural Science Foundation of China(No.50206008)
For calculating the resonance frequency of practical resonance pipes more precisely, two methods are presented, which are the method of acoustic pressure simulation and the method of minimum point of standing wave. Bo...
Propagation of sound in pipes with gas flow of high temperature
《Chinese Journal of Acoustics》1990年第3期221-230,共10页ZHAO Songling(Institute of Acoustics , Tongji University) 
In this paper, propagation of sound in pipes under the influence of a gas flow of high temperature is investigated . The analysis in the paper is based on the fundamental equations of fluid mechanics . Approximate for...
