Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: The structure of a shock wave in a partially ionized gas, which is in thermal on-equilibrium ahead of the shock wave, is investigated. A method is developed to solve this problem by separating it into two parts. First the structure of the shock wave associated with the mixture of ions and atoms, which are assumed to behave alike through the shock transition, is taken to be of the Mott-Smith form. Then the behavior of electrons as they pass through this ion-atom shock is analyzed. Using this method, calculations are made for the shock wave structure in partially ionized argon for Mach numbers equal to 8, 10 and 12, and for the values of the lectron-ion temperature ratio ahe d of the shock wave equal to 3, 5 and 8.

Available in PDF, EPUB and Kindle. Book excerpt: A combined experimental and numerical investigation was conducted on the flat plate boundary layer flow of a partially ionized gas. A free molecule cylindrical Langmuir probe was used to measure charged particle density, electron temperature and plasma potential distributions in the boundary layer. The ambipolar diffusion flux to the plate surface was determined by an array of flush-mounted surface electrodes. A probe size-study was carried out and an empirical formula was obtained to make correction for the sheath-fringing field effect on ion current collection to small flush probes. Numerical integrations were made of the charged species conservation and electron energy equations in the quasi-neutral region of the boundary layer for a thin plasma sheath. Mechanisms leading to the cooling of the electron gas were investigated. Numerical profiles of charged particle density, electron temperature and plasma potential compared favorably with experimental results. Ambipolar diffusion fluxes predicted theoretically agreed very well with the measured flush probe ion saturation current. The validity of employing such a flush-mounted surface electrode in determination of the free stream charged particle density was then established. (Author).
