They observed that the flame propagation velocity inside the main chamber increased significantly using supersonic jets.
0] is ultrasonic vibration amplitude, and [omega] is angular frequency, u is propagation velocity of ultrasonic in the polymer melt, and influenced by the experimental environment such as the neglected temperature.
The ultrasonic wave propagation velocity was obtained using an ultrasound device (Steinkamp/BP7, Germany) with emission of ultrasonic pulse at frequency of 45 kHz and equipped with two flat-section transducers (Figure 1A), one emitter and the other receiver of the pulse.
On the other hand, we have the methods that use ultrasound, using the relationship between the acoustic impedance, propagation velocity and density.
The authors address the implications of causality and passivity and their connection with radiation conditions, Lorentz reciprocity, scattering problems, finite propagation velocity of wavefronts, and Bloch-wave representations in periodic media.
The largest flame propagation velocity is usually obtained near the equivalence ratio of 1 with other parameters unchanged.
The measured wave propagation velocity is equal to 3500 m.
The propagation velocity of transverse acoustic wave over controlled environment, i.
Their small propagation velocity and high sensitivity to disturbances confined to a superficial region have long been exploited in electronic signal processing and sensor applications.
The propagation velocity of ultrasonic waves from measurements in trees is numerically different from the velocity obtained from measurements in logs, even in freshly felled logs, and the latter velocity is better correlated with the quality of the wood.
By considering the propagation velocity (dispersion) of these flows in both horizontal and vertical direction, we will have the following equations:
These length scales are also almost proportional to rupture duration, because the rupture propagation velocity is also scale independent.
