Sentence examples for lowest phase velocity from inspiring English sources

The theory predicts three modes of wave propagation, one of which is essentially torsional in character; a second mode may be identified with predominatly flange bending according to the second branch of Timoshenko beam theory whilst a new mode involves individual flange torsion with asymmetric web deformation, and has the lowest phase velocity except at the longest wavelength.

It is shown that the graphene Cherenkov radiation can be excited by a moving electron at a relative lower speed, which greatly reduces the difficulty for the Cherenkov radiation realization due to the low phase velocity and high field confinement of graphene plasmons.

Sites T22 and T19 had low phase velocities (~400 m/s) at lower frequencies that represent deep parts of the sediment layer.

Gas-liquid stratified flow is the most vulnerable flow regime for sand deposition, owing to the low phase velocities that occur in this flow regime.

Rao et al. [8] investigated the existence of a new extremely low-phase velocity dust acoustic waves (DAW) in an unmagnetized dusty plasma.

In the case of short pore separation and a low dispersed phase velocity, the drop formation process was uniform, resulting in an emulsion with a narrow drop size distribution, and a dispersed phase flux of 500 L/m2 h.

In this paper, the S0-mode Lamb wave phase velocity at low frequency range is chosen to characterize fatigue damages accumulated in composite laminates under cyclic loadings.

Furthermore, as the angular velocity increases, the phase velocities of the transverse waves decrease and, in general, the finite rotation has more significant effect on the phase velocity of low frequency transverse waves as compared to the high frequency waves.

The slight difference in the second layer between the sites may have been caused by the characteristics of the phase velocity curves at low frequencies.

Using the measured data, the DNS results and a review of the models used for comparison it was found that the phase velocity decreases at low frequencies.

The results showed that while the influence of the randomly distributed micro-cracks on the phase velocity of the low frequency S0 fundamental waves could be neglected, significant ultrasonic nonlinear effects caused by the randomly distributed micro-cracks was discovered, which mainly presented as a second harmonic generation.
