Available in PDF, EPUB and Kindle. Book excerpt: All numerical simulations have some inherent error associated with the results but minimizing the error may also maximize the processing time of the simulation. The particle collision model used for this paper is Monte Carlo Collisions. The results of the simulations were compared to a vacuum tank experiment conducted at the Air Force Research Laboratory. The results were compared for simulations with and without collisions using different neutral densities and levels of complexity for particle collisions. The effect of particle collisions is evident in the results of the simulations. Increasing the neutral density of the simulation does not have a major impact on the results in the plume region. Outside the plume region the particle collisions can affect the results by an order of magnitude or greater.
Book Synopsis Plasma Simulations by Example by : Lubos Brieda
Download or read book Plasma Simulations by Example written by Lubos Brieda and published by CRC Press. This book was released on 2019-12-13 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of plasmas is crucial in improving our understanding of the universe, and they are being increasingly utilised in key technologies such as spacecraft thrusters, plasma medicine, and fusion energy. Providing readers with an easy to follow set of examples that clearly illustrate how simulation codes are written, this book guides readers through how to develop C++ computer codes for simulating plasmas primarily with the kinetic Particle in Cell (PIC) method. This text will be invaluable to advanced undergraduates and graduate students in physics and engineering looking to learn how to put the theory to the test. Features: Provides a step-by-step introduction to plasma simulations with easy to follow examples Discusses the electrostatic and electromagnetic Particle in Cell (PIC) method on structured and unstructured meshes, magnetohydrodynamics (MHD), and Vlasov solvers Covered topics include Direct Simulation Monte Carlo (DSMC) collisions, surface interactions, axisymmetry, and parallelization strategies. Lubos Brieda has over 15 years of experience developing plasma and gas simulation codes for electric propulsion, contamination transport, and plasma-surface interactions. As part of his master’s research work, he developed a 3D ES-PIC electric propulsion plume code, Draco, which is to this date utilized by government labs and private aerospace firms to study plasma thruster plumes. His Ph.D, obtained in 2012 from George Washington University, USA, focused on a multi-scale model for Hall thrusters utilizing fluid-kinetic hybrid PIC codes. He has since then been involved in numerous projects involving development and the use of plasma simulation tools. Since 2014 he has been teaching online courses on plasma simulations through his website: particleincell.com.

Download or read book Fundamentals of Electric Propulsion written by Dan M. Goebel and published by John Wiley & Sons. This book was released on 2008-12-22 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

Download or read book Computational Modeling of Expanding Plasma Plumes in Space Using a PIC-DSMC Algorithm written by and published by . This book was released on 1997 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive computational model of the plume of a Hall Thruster is presented. Spacecraft-plume interaction issues are addressed by studying how a partially ionized plasma expands in three dimensions and interacts with the surfaces it encounters. A quantitative analysis of fundamental parameters is used to show that the plume is an unmagnetized, quasi-neutral plasma in which Charge Exchange collisions play a significant role. The electrons are shown to be isothermal and collisionless and the electron momentum equation is shown to reduce to the Boltzmann relationship. An axisymmetric computational model of the plume is described in detail. The model combines the Particle-in-Cell (PIC) and Direct Simulation Monte Carlo (DSMC) methods to create a quasi-neutral PIC-DSMC model. The resulting model is relatively fast and is used to model meter scale objects on workstation class computers. Comparisons are made to experimental data from multiple sources. The model is shown to have good agreement with macroscopic quantities such as current densities and sputtering rates but poor agreement with microscopic quantities like the ion distribution function. Disagreement is thought to be due to inadequicies in the plasma source model. Further results are presented showing the thruster operating in vacuum. 'Rules of thumb' are recommended for scaling erosion rates.
