Kinetic Simulation of Ion Thruster Plume Neutralization in a Vacuum Chamber
Keita Nishii, Deborah Levin
The electrical environment of a ground vacuum testing chamber creates facility effects for gridded ion thrusters. For example, it is well known that the plume from the thruster gen…
Three-Dimensional Kinetic Simulation of an Ion Thruster Plume with Carbon Backsputtering in a Vacuum Chamber
Keita Nishii, Deborah A. Levin
Gridded ion thrusters are tested in ground vacuum chambers to verify their performance when deployed in space. However, the presence of high background pressure and conductive wall…
Excitation of electrostatic solitary waves and surface waves in ion beam neutralization process
Nakul Nuwal, Igor D. Kaganovich, Deborah A. Levin
Unusually long electrostatic solitary waves (ESWs) are discovered in 2D and 3D Particle-in-Cell studies of the process of ion beam neutralization by electron emission from filament…
Kinetic modeling of three-dimensional electrostatic-solitary and surface waves in beam neutralization
Nakul Nuwal, Deborah A. Levin, Igor D. Kaganovich
This work studies the fundamental plasma processes involved in the neutralization of an ion beam's space-charge by electrons emitted by a filament using Particle-in-Cell simulation…
Linear stability analysis of hypersonic boundary layers computed by a kinetic approach: A semi-infinite flat plate at Mach 4.5 and 9
Angelos Klothakis, Helio Quintanilha, Saurabh S. Sawant +3
Linear stability analysis is performed using a combination of two-dimensional Direct Simulation Monte Carlo (DSMC) method for the computation of the basic state and solution of the…
Kinetic modelling of three-dimensional shock/laminar separation bubble instabilities in hypersonic flows over a double wedge
Saurabh S. Sawant, Vassilios Theofilis, Deborah A. Levin
Linear global instability of the three-dimensional (3-D), spanwise-homogeneous laminar separation bubble (LSB) induced by shock-wave/boundary-layer interaction (SBLI) in a Mach 7 f…
