For cases without afterburner, the normalized spectra agrees well regardless of the nozzle scale and total temperature where the velocity index lies from n = 7.7 to 9.2, and the correlation factor between the two facilities is shown to be about 1 dB. For the case with afterburner, the ...
This simple scaling property is shared by a more complete shock-cell noise model that accounts for the spatially extensive noise-sources. This simple scaling can be contrasted with the empirically determined amplitude factor in Tam's formula [338] which shows good agreement with data but with no...
High quality jet noise spectral data measured at the Aeroacoustic Propulsion Laboratory at the NASA Glenn Research Center is used to examine a number of jet noise scaling laws. Configurations considered in the present study consist of convergent and convergent-divergent axisymmetric nozzles. Following ...
Magnetic reconnection naturally occurs in the turbulent plasma at the end of the magnetic nozzle where the jet collimation weakens. The multi-scale nature of magnetic reconnection in a turbulent region provides a viable solution to the observed minute-scale variability, indicating structures much ...
The present definition of the energy separation factor renders its distribution independent of the jet Reynolds number; except for axial locations between about 0.3D and 4D. The development of energy separation in the region close to the nozzle exit is faster when the jet Reynolds number is ...

Soraya et al. introduced fabrication of micro-nanocapsules by a new electrospraying technique using coaxial E-Jet printing. Hai-liang et al. used coaxial printing method ...
plasma upstream of the throat of a diverging nozzle (microwave thrusters). Devices of this class are thus hybrid electrothermal and electrostatic and, indeed, since some of them also employ magnetic fields to confine and direct the flow, may actually embody all three classes of interaction. ...
The results demonstrate a generally linear scaling of the vibrational excitation with cross section, except for cross sections that produce excitation rates in excess of the VHS gas kinetic rate. The jet exit-plane boundary layer profile was found to be a factor in the amount of CO excited ...
Before the experiment, we performed 3D optical (using a He-Ne, 633 nm wavelength laser probe) tomography measurements to characterize the rectangular gas profile in the output of the nozzle using Argon gas. It should be noted that the difference in gas flow found by our measurement and ...
However, standard flow chromatography sensitivity has been the limiting factor in wide spread use for LC/MS proteomics analysis. Jet Stream proteomics uses Agilent's high performance mass spectrometers incorporating iFunnel technology to change this paradigm by achieving new levels of sensitivity for ...
