Pages : 123
Book Description
Shock structure experiments were carried out in a radio frequency heated, steady state, low density, partially ionized argon plasma jet. The primary diagnostic tool was the aligned cylindrical free molecule Langmuir probe used to probe a normal shock wave. Spatial resolution was 13% of the heavy particle shock thickness, thus details of electron temperature, ion number density, and plasma potential are available through the shock. The electron temperature rise was observed to precede the heavy particle shock. The plasma potential converted from floating potential according to the theory of Laframboise was in substantial agreement with changes in plasma potential obtained from a numerical quadrature of the generalized Ohm's Law assuming zero current. A quantitative explanation of the dark space observed to precede partially ionized gas shocks is provided by comparing the collisional-radiative recombination rate calculated with observed electron temperature and number density to the luminosity of the flow. The results of integrating the electron energy equation including the effect of recombination energy transfer was compared to the data to show that the fraction of ionization energy given to the electron gas was not constant through the shock.

An Experimental Study of the Shock Struture in a Partially Ionized Gas
Preliminary Experimental Investigation of the Ionized Gas in Front and Behind a High Velocity Shock in Argon

Pages : 62
Book Description
This report presents the preliminary results of an experimental investigation of electromagnetic properties of an ionized gas induced by a shock wave in a shock tube. The shock velocity has been measured using a microwave technique based on the resonat properties of the tube as a waveguide. Electrostatic measurements have been conducted in the ionized gas; they show that the ionized gas becomes positively charged with respect to the wall of the tube. (Author).

Shock Wave Structure in a Fully Ionized Gas Based on Multi-component Fluid Theory
Author: Huon Li
Publisher:
ISBN:
Category : Differential equations
Languages : en
Pages : 132
Book Description
The multi-component continuous approach for the investigation of the gasdynamics of a plasma is presented. More information about the flow properties of a plasma can be obtained than from the classical magnetohydrodynamic approach. Also, the resulting equations appear to be more easily solved than the Blotzmann equation of classical kinetic theory. The basic macroscopic conservation equations for a non-reacting multi-component plasma are presented. The fluid properties of each component are referred to the mean velocity of that component. Therefore, no limitations are placed on the magnitude of the diffusion velocities. The effects of electric and magnetic fields are included. The equations for a two-component mixture are used to study the structure of a shock wave in a fully-ionized hydrogen gas. It is assumed that the momentum exchange and energy exchange between the ions and electrons are important because of the strong Coulomb forces present. (Author).
