The interaction between an argon plasma jet excited using microsecond duration voltage pulses and a liquid target was examined using Thomson scattering to quantify the temporal evolution of the electron density and temperature. The electrical resistance between a liquid target and the electrical ground w...
An experiment of impact between 450 m/s water jets and polymethylme-thacrylate (PMMA) materials with complex surface geometry was conducted. The testing surfaces were a corner, step change, surface-breaking notch, inclined surface, etc. Stress waves propagation in the solid such as reflection, ...
6(c). It is found in the SEM images that with the increase of impact pressure, wrinkles appeared on the surface, and the contact angle decreased by 2° on average after the experiment. Sign in to download hi-res image Fig. 6. (a) The change of hydrophobicity with falling height and ...
Although no known asteroid poses a threat to Earth for at least the next century, the catalogue of near-Earth asteroids is incomplete for objects whose impacts would produce regional devastation1,2. Several approaches have been proposed to potentially prevent an asteroid impact with Earth by deflect...
The motion of a kinematic discontinuity in the liquid film on the wall due to the drop impact, the formation of the upward jet at this kinematic discontinuity and its elevation are analysed. Four main regions of the drop and film are considered: the perturbed liquid film on the wall inside...
Electron-impact ionization of (NH 3) n cluster. (1 n10) has, been investigated in a supersonic-jet experiment using a double-focusing mass spectrometer. A ... K Stephan,JH Futrell,KI Peterson,... - 《International Journal of Mass Spectrometry & Ion Physics》 被引量: 73发表: 1982年 The...
In Fig. 1d we show the splatter patterns left by the ferrofluid stains, from which we can quantitatively measure the amount of splash for stage-3. Clearly, our experiment enables a quantitative study of shape’s influence on all three stages. Spreading dynamics governed by the superellipse ...
In this case the effect of the distance between two opposed nozzles was examined. For a lab-scaled fluidized bed opposed jet mill the effects of gas pressure and hold-up were investigated. Relative particle velocities were found to be significantly lower than the gas velocities, while the ...
