Temperature dependence of ultrasonic Grüneisen parameter and ultrasonic attenuation in alkali halides104(1998); http://dx.doi.org/10.1121/1.423240View Description Hide Description
Temperature dependence of ultrasonic attenuation and ultrasonic Gruneisen parameter are investigated in alkali halides in the range 80–300 K. The calculations use a computer program, developed by the authors, for implementing Nava’s modified formulation of Woodruff’s theory. These calculations are done for NaCl, NaF, and LiF for longitudinal and shear waves along the , , and  directions. Compared to calculations based on original Mason formulation, it was found that in most cases the results are in better agreement with the experimental data. The results also help to throw some light on relative merits of different theories of attenuation.

A theory on acoustic streaming generated by Lamb waves propagating in a thin composite membrane was developed. Using this theory, the mass-transport velocity in water, which is loaded on a 4-μm-thick membrane, due to Lamb waves at 4.7 MHz was calculated. The results are in good agreement with the experimental values measured by Moroney et al. [Appl. Phys. Lett. 59, 774 (1991)].
