Book Description

Abstract: Species composites of Ag-N2, Ag-H2 and Ag-He plasmas in the temperature range of 3, 000-20, 000 K and at 1 atmospheric pressure were calculated by using the minimization of Gibbs free energy. Thermodynamic properties and transport coefficients of nitrogen, hydrogen and helium plasmas mixed with a variety of silver vapor were then calculated based on the equilibrium composites and collision integral data. The calculation procedure was verified by comparing the results obtained in this paper with the published transport coefficients on the case of pure nitrogen plasma. The influences of the silver vapor concentration on composites, thermodynamic properties and transport coefficients were finally analyzed and summarized for all the three types of plasmas. Those physical properties were important for theoretical study and numerical calculation on arc plasma generated by silver-based electrodes in those gases in sealed electromagnetic relays and contacts.







Transport Properties of Dense Plasmas


Book Description

The idea to write this volume arose in May, 1979 on the "Annual Seminar on Sta tistical Physics" in Lähnwitz near Güstrow, a nice resort place of the Pädagogische Hochschule Liselotte Herrmann Güstrow, where most of the authors were present. The participants of this seminar agreed in the general opinion that the transport properties of charged particle systems starting from ionized gases and ending with liquid metals should be interpreted in a unique way. The basic method of such a uni fied theory which is still in "status nascendi" nowadays, should be the statistical physics of systems with Coulombic interactions. The first two chapters of this volume are devoted to mainly experimental aspects in investigating high density plasmas. After transport theory is presented in chapter 3., two special problems are considered being of interest in the theory of high density plasmas: the problem of bound states in kinetic theory (chapter 4.) and the theory of liquid metals (chapter 5.), which may be considered as weakly coupled nonideal plas mas. Besides transport properties also thermodynamic properties of den se Coulomb systems have been discussed in chapters 1. and 5. The theory of thermodynamic properties of plasmas has been given in a previous volume (Nr. 5) of this series.
