2018年8月1日 · Shock waves and the associated phenomena generated by strongly ablating meteoroids with sizes greater than a few millimeters in the lower transitional flow regime of the Earth’s atmosphere are the least explored aspect of meteor science.

When the 2013 meteor entered into the Earth's atmosphere with an energy release equivalent to 100 or more kilotons of TNT, dozens of times more powerful than the atomic bomb dropped on Hiroshima, the meteor's shock wave produced damage as in a supersonic jet's flyby (directly underneath the meteor's path) and as a detonation wave, with the ...

2024年6月11日 · The paper presents the results of studies of shock waves propagating in the atmosphere. These results were obtained by recording sound waves generated by a shock wave. It has been shown that it takes approximately two seconds for a shock wave to form.

2018年8月1日 · Shock waves are generated by almost all strongly ablating and sufficiently large meteoroids that enter denser regions of the Earth’s atmosphere and reach the lower transitional flow regime as defined by the Knudsen number (provided that these meteoroids retain sufficient mass and velocity close to that of the initial pre-atmospheric velocity).

Shock waves and the associated phenomena generated by strongly ablating meteoroids with sizes greater than a few millimeters in the lower transitional flow regime of the Earth’s atmosphere are the least explored

Abstract-A numerical investigation of shock wave propagation in open atmosphere is presented to observe the shock wave decaying phenomena due to expansion in the free space. By examining different parameters (Pressure, velocity and density) of the upstream and downstream flow

2008年5月1日 · The present report is aimed at a comparison of waveforms and spectra of laser-induced acoustic shock waves generated by single liquid and solid aerosol particles, monodisperse liquid and solid aerosol particle ensembles, and outdoor atmospheric aerosol and elucidation of their special features.

2025年1月23日 · Larger meteors entering the atmosphere create shock waves which can be detected on the ground as low-frequency vibration known as infrasound. Shock waves result when the matter through which the wave is passing is …

1994年4月1日 · The waves generated by pulse sources at the ground can have shock wave characteristics upon reaching the upper layers of the atmosphere. This paper proposes a new computation method based on studies of shock propagation in ray tubes for laboratory experiments and attempts to adapt this method to atmospheric propagation.

2020年2月15日 · This Special Issue is focused on shock waves and their effects on planetary atmospheres, including shock wave generation, propagation and attenuation, as well as source localization and characterization.
