Temperature has a complex effect on acoustic dispersion in dilute gases. In this paper, the effect of temperature on the acoustic dispersion of dilute gases is analyzed theoretically and experimentally. Theoretically, the Navier–Stokes (NS) equatio

For soil liquefaction prediction from multiple data sources, this study designs a hierarchical machine learning model based on deep feature extraction and Gaussian Process with integrated domain adaption techniques. The proposed model first combines

The variation of sound speeds of air and nitrogen gas at temperatures from 15 to −80 °C, and at gas pressures from 105 to 150 Pa have been measured in a KM2G space simulator. The objective is to provide the primary acoustic parameters to set up a

Future Martian missions might carry acoustic anemometer, microphone, or ultrasound inspector. These Martian acoustic probes all need to be specifically designed to adapt to the tenuous Martian atmosphere. To aid the design, experiments have been carr

Guided waves in plates and cylinders exhibit the backward propagation that group and phase velocities have opposite directions. Backward waves might be used to control the acoustic energy flux. The existence of backward waves in acoustic waveguides h

Hollow cylinders often exhibit backward propagation modes whose group and phase velocities have opposite directions, and these exhibit a minimum possible frequency at which the group velocity vanishes at a nonzero wavenumber. These zero-group-velocit

This paper first reviews a method of simulating the propagation characteristics of guided waves in multilayered coaxial cylindrical elastic solid media. Secondly, this method is used to investigate the properties of the guided waves for the ultrasoni

In clad rods, the dispersion properties of firstorder flexural [F(1, 1)] modes can differ from other modes. Normal and Stoneley modes and the existence criteria for four F(1, 1) modes are investigated. We focus on low-frequency anomalous dispersion,

This paper considers the propagation of Stoneley modes along the interfaces of three-layered concentric cylindrical solid media in order to assist in the design of ultrasonic transmission rods. The phase velocity dispersion curves and amplitude distr
