PIC Simulations of the MS4 Thruster

open access: yesFrontiers in Physics, 2022
Particle-in-Cell (PIC) simulations are used to model the MS4 test thruster of Thales Deutschland. Given as input the geometric shape, material components, magnetic field and the operating parameters of the experiment, the model is able to reproduce the ...

Digital In-Line Holography of Condensed-Phase Particles in Solid Rocket Motor Plume

open access: yesFrontiers in Physics, 2022
Condensed phase particles (CCPs) of plume flows in solid rocket motors (SRMs) are one of the major causes of smog and other signal characteristics, which leads to attenuation of weapons guidance system signals.

Ozone Depletion in Tropospheric Volcanic Plumes: From Halogen-Poor to Halogen-Rich Emissions

open access: yesGeosciences, 2018
Volcanic halogen emissions to the troposphere undergo a rapid plume chemistry that destroys ozone. Quantifying the impact of volcanic halogens on tropospheric ozone is challenging, only a few observations exist.

Secondary Intrusion Formation of Multiphase Plumes

open access: yesFrontiers in Marine Science, 2021
This work presents a new laboratory study for understanding secondary intrusions in multiphase plumes in quiescent, stratified environments. The study is driven by field observations of secondary intrusions during the Deepwater Horizon (DWH) oil spill ...

Magnetic Signatures of a Plume at Europa During the Galileo E26 Flyby

open access: yesGeophysical Research Letters, 2019
We analyze the magnetic field perturbations observed near Jupiter's icy moon Europa by the Galileo spacecraft during the E26 flyby on 3 January 2000. In addition to the expected large‐scale signatures of magnetic fieldline draping and induction, the E26 ...

Geodynamic process and its geologic manifestations in the continents

open access: yesГеофизический журнал, 2018
The data on the composition of the mantle and crust, results of experimental studies on melting under the pressure interval 0,5—0,7 GPa and temperatures 500—2000 °C have been integrated.

Interaction of an Eulerian flue gas plume with wind turbines [PDF]

open access: yes, 2010
The reduced availability of sites with the requisite wind resource, planning permission and public acceptance for the placement of wind turbines poses a significant challenge to future expansion of the wind energy industry.

The subtropical global plume in the Pacific Exploratory Mission-Tropics A (PEM-Tropics A), PEM-Tropics B, and the Global Atmospheric Sampling Program (GASP): How tropical emissions affect the remote Pacific [PDF]

open access: yes, 2002
[1] An extended southern subtropical plume of CO meanders>15,000 km around the world, gradually spreading around 20 S. This southern pollution plume is most noticeable in the burning season, southern spring; a similar subtropical plume appears in the ...

Free-flight responses of Drosophila melanogaster to attractive odors [PDF]

open access: yes, 2006
Many motile organisms localize the source of attractive odorants by following plumes upwind. In the case of D. melanogaster, little is known of how individuals alter their flight trajectories after encountering and losing a plume of an attractive odorant.
