Titre de série : Journal of the acoustical society of America, Vol.91 No.5 Titre : Flexure waves in elastic rods Type de document : articles et extraits Auteurs : B. D. Coleman, Auteur ; E. H. Dill, Auteur Année de publication : 1992 Importance : p.2663-2673 Langues : Français (fre) Résumé : The order-1 theory of the dynamics of homogeneous elastic rods is treated with the emphasis on twist-free bending motions of inextensible rods. Various forms of the governing equations for such planar motions are presented, and their traveling wave solutions are shown to result in curves of the same form as those in Euler's theory of equilibrium configurations. Traveling waves are called subsonic or supersonic in accord with whether their speed is less than or greater than (E/rho)1/2 with E the tensile modulus and rho the density. The solitary traveling waves are loops and are given by elementary functions. At each prescribed level of tension below a critical value, for both subsonic and supersonic waves, the larger the loop the faster the wave. The periodic traveling waves, both with and without inflexion points, are given by elliptic functions and integrals. Small amplitude sinusoidal waves are a limiting case of inflexional waves. The solitary waves are obtainable as appropriate limits of both inflexional and noninflexional waves. Although, in general, traveling waves are motions of rods of infinite length, there are traveling waves that are possible planar modes of motion for rods of finite length with joined ends. A rod with such a traveling wave forms a figure eight in the inflexional case and a circular ring in the noninflexional case.

Effect of polymer surface activity on cavitation nuclei stability against dissolution / T. M. Porter
in The journal of the Acoustical Society of America
Titre de série : Journal of the acoustical society of America, Vol.116 No.2 Titre : Effect of polymer surface activity on cavitation nuclei stability against dissolution Type de document : articles et extraits Auteurs : T. M. Porter, Auteur ; L. A. Crum, Auteur ; A. S. Hoffman, Auteur ; P. S. Slayton, Auteur Année de publication : 2004 Importance : p.721-728 ISBN/ISSN/EAN : 0001-4966 Langues : Français (fre) Résumé : The persistence of acoustic cavitation in a pulsed wave ultrasound regime depends upon the ability of cavitation nuclei, i.e., bubbles, to survive the off time between pulses. Due to the dependence of bubble dissolution on surface tension, surface-active agents may affect the stability of bubbles against dissolution. In this study, measurements of bubble dissolution rates in solutions of the surface-active polymer poly(propyl acrylic acid) (PPAA) were conducted to test this premise. The surface activity of PPAA varies with solution pH and concentration of dissolved polymer molecules. The surface tension of PPAA solutions (55-72 dynes/cm) that associated with the polymer surface activity was measured using the Wilhelmy plate technique. Samples of these polymer solutions then were exposed to 1.1 MHz high intensity focused ultrasound, and the dissolution of bubbles created by inertial cavitation was monitored using an active cavitation detection scheme. Analysis of the pulse echo data demonstrated that bubble dissolution time was inversely proportional to the surface tension of the solution. Finally, comparison of the experimental results with dissolution times computed from the Epstein-Plesset equation suggests that the radii of residual bubbles from inertial cavitation increase as the surface tension decreases.

Titre de série : Journal of the acoustical society of America, Vol.76, No.S1 Titre : Mie Scattering as a Technique for the Sizing of Air Bubbles Type de document : articles et extraits Auteurs : Gary M. Hansen, Auteur Année de publication : 1984 Importance : p. S31 Langues : Anglais (eng) Résumé : A technique has been developed which allows the radius of a bubble in a fluid to be accurately measured without disturbing the bubble. Results are presented which show that radius measurements of single air-bubbles in water can be achieved by shining a He-Ne laser on the bubble and measuring the light scattered at 80 degrees. Light intensity measurements at a scattering angle of 55 degrees were used to calibrate a photodiode detection system and to demonstrate the correlation of data with Mie scattering theory. The photodiode was then moved to 80 degrees for actual radius measurements. This technique was accurate to within 3% for bubbles with radii less than 80 microns.

Howe, Auteur Année de publication : 1995 Importance : p.1723-1730 Langues : Anglais (eng) Résumé : A frequency-dependent model is proposed for the eddy viscosity controlling the momentum and thermal wall boundary layers formed when an acoustic wave interacts with a low Mach number turbulent boundary layer whose thickness is much smaller than the acoustic wavelength. This is used to determine the effective acoustic admittance of the boundary layer, and to predict the attenuation of sound reflecting from a plane wall boundary layer, and low-frequency sound propagating in fully developed turbulent pipe flow. The predictions are shown to compare well with a recent experimental study of acoustic attenuation in pipe flows. ©1995 Acoustical Society of America.
