Solving the Boltzmann equation to obtain electron transport coefficients and rate coefficients for fluid models
Fluid models of gas discharges require the input of transport coefficients and rate coefficients that depend on the electron energy distribution function. Such coefficients are usually calculated from collision cross-section data by solving the electron Boltzmann equation (BE). In this paper we present a new user-friendly BE solver developed especially for this purpose, freely available under t...
متن کاملSimulation of electron thermal transport in H-mode discharges
Electron thermal transport in DIII-D H-mode tokamak plasmas ͓J. L. Luxon, Nucl. Fusion 42, 614 ͑2002͔͒ is investigated by comparing predictive simulation results for the evolution of electron temperature profiles with experimental data. The comparison includes the entire profile from the magnetic axis to the bottom of the pedestal. In the simulations, carried out using the automated system for tran...
متن کاملElectron Transport Data in N2-o2 Streamer Plasma Discharges
A multi-term theory for solving the Boltzmann equation and a Monte Carlo simulation technique are used to investigate the electron transport in mixtures of molecular nitrogen and oxygen. We investigate the way in which the transport coefficients and spatially resolved transport data are influenced by the amount of O2 in the mixture. This study was initiated in order to obtain the transport data...
متن کاملChaotic scattering theory of transport and reaction-rate coefficients.
The chaotic scattering theory is here extended to obtain escape-rate expressions for the transport coefficients appropriate for a simple classical fluid, or for a chemically reacting system. This theory allows various transport coefficients such as the coefficients of viscosity, thermal conductivity, etc., to be expressed in terms of the positive Lyapunov exponents and Kolmogorov-Sinai entropy ...
متن کاملPulse Townsend Measurement of Electron Swarm Parameters at Low Pressure
The pulse Townsend method was used to investigate electron swarm at more than 665 mbar. We introduced a new convenient way to obtain swarm parameters from the experiments at less than 133 mbar. The validity of the new presented method was confirmed by the Monte Carlo simulation. This method was applied to obtain swarm parameters in nitrogen at pressure region from 0.532 to 6.65 mbar. The result...
