High Performance Computing in Science and Engineering '08
We numerically solve the Boltzmann equation for rarefied, non-continuum plasma flows, making use of well known approaches as PIC (Particle in Cell) and as DSMC (Direct Simulation Monte Carlo). ... This paper describes the numerical modeling of rarefied plasma flows under conditions where continuum assumptions fail. ... The main propulsion system will consist of a cluster of instationary magnetoplasmadynamic (IMPD) thruster, also known as pulsed plasma thruster. ...doi:10.1007/978-3-540-88303-6_40 fatcat:xvny5kmd7bbofg7t4gsprlmosa
Among the described electric propulsion systems are recent developments in the field of applied field MPD but also from high power hybrid thrusters. ... In addition, new concepts such as the hybrid systems Thermal-Inductively heated Hybrid-Thruster of the University of Stuttgart (TIHTUS) and the so-called Coupled Tether/Ion Engine Propulsion (CETEP) are ... Acknowledgement We thank all partner institutions and the German Research Foundation (DFG) for the support of the AF-MPD development. ...doi:10.2322/tstj.7.tb_5 fatcat:433ykhw2fzgircx2hqdapngilq
plasma flows is under development, making use of well known approaches from PIC (Particle in Cell) and DSMC (Direct Simulation Monte Carlo). ... Within the project "Modeling and Simulation on High Performance Computers", which is funded by the Landesstiftung Baden-Württemberg, a scheme for solving the Boltzmann equation for rarefied, non-continuum ... The main application for this scheme is the modeling of an instationary magnetoplasmadynamic (IMPD) thruster, also known as pulsed plasma thruster (PPT). ...doi:10.1051/proc:2007004 fatcat:mnvetn546veajpd25k4cvhhfzm
A better physical understanding of electrical space propulsion systems like Pulsed Plasma Thrusters requires the numerical modelling and simulation of highly rarefied plasma flows. ... A Taylor series expansion up to second order in velocity of the post-collision distribution functions and the adoption of a cut-off value for the impact parameter permits the final integration of the Boltzmann ... Mission BW-1 will be accomplished by a Pulsed Plasma Thruster PPT, named SIMPLEX (Stuttgart Instationary MagnetoPlasmadynamic Thruster for Lunar Exploration). ...doi:10.18419/opus-3795 fatcat:mzggpwyxwverhnvevmdis34xfq
Mission BW-1 will be accomplished by a Pulsed Plasma Thruster PPT, named SIMPLEX (Stuttgart Instationary MagnetoPlasmadynamic Thruster for Lunar Exploration). ... , which is one basic concept of the hybrid PIC/DSMC code development  . ... Three Dimensional Solution of the Lenard-Bernstein Model In the following we briefly sketch the analytical solution of the Lenard-Bernstein model (see,  for the one-dimensional and [37, 46] for ...doi:10.5445/ir/200076872 fatcat:pyapgk27azdptcgdx6cvhcwy3q
