This book was released on 1965 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: From measurements of the temperature dependence of the amplitude of ultrasonic pulses propagated over a fixed path in liquid helium, the attenuation coefficient has been determined at the six frequencies 1.00, 2.02, 3.91, 6.08, 10.2, and 11.7 Mc/sec, at temperatures extending down to 0.2K. Below 0.6K, the observed variation of the absorption coefficient a (1/cm) with frequency f (Mc/sec) and temperature T (K) can be represented by the empirical equation a=0.11 (f to the 2/3 power)(Tcubed). This behavior differs from that predicted by several existing theories that are based upon the threephonon or four-phonon interaction between longitudinal acoustic quanta and thermal phonons. Over the temperature interval 0.6-0.8K, the measured attenuation is somewhat greater than would be expected from an extrapolation of the results below 0.6K into this temperature region. A comparison of the data with some calculations by Khalatnikov suggests that the additional absorption arises from thermal conduction in the normal fluid. An equation that is analogous to the classical Kirchhoff expression adequately accounts for this contribution to the total absorption, even at temperatures for which the lifetime of the thermal phonons exceeds the period of the sound wave.

Download or read book Absorption and Dispersion of Ultrasonic Waves written by Karl F. Herzfeld and published by Academic Press. This book was released on 2013-10-22 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorption and Dispersion of Ultrasonic Waves focuses on the influence of ultrasonics on molecular processes in liquids and gases, including hydrodynamics, energy exchange, and chemical reactions. The book first offers information on the Stokes-Navier equations of hydrodynamics, as well as equations of motion, viscosity, formal introduction of volume viscosity, and linearized wave equation for a nonviscous fluid. The manuscript then ponders on energy exchange between internal and external degrees of freedom as relaxation phenomenon; effect of slow energy exchange on sound propagation; different ways of evaluating the dispersion curve; and exact calculation of absorption and dispersion. The text examines the effects of chemical reactions, thermodynamic theory of relaxation, and mixtures. The book also evaluates the absorption of high intensity sound waves, ratio of relaxation absorption to classical absorption at maximum, and gas mixtures. Discussions also focus on translational relaxation in monatomic gases, linear triatomic molecules, and results for rotational relaxation. The manuscript is a dependable source of data for readers interested in the absorption and dispersion of ultrasonic waves.
