Abstract
The phenomena arising during the propagation of acoustic waves in narrow tubes with variable cross sections are studied. A special law of cross-sectional variation is defined for the tube. The mode of wave tunneling through a gradual narrowing is investigated. The influence of the added mass on the boundaries of the narrowing area of the tube is considered. The frequency dependences of the coefficient of wave transmission over energy are constructed with allowance for the added mass. Features of discribing dissipative effects in tubes are noted.
期刊介绍:
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
