Nonequilibrium Phenomena in Flowing Plasmas and at High Magnetic Fields.

Abstract

This report summarizes work accomplished during the period February 15, 1974 to February 14, 1975, and describes at greater length results obtained in two areas. The first area is concerned with the effects of random inhomogeneities on the performance of MHD generators. A nonlinear theory is presented which accounts for the lowering of the effective electrical conductivity and Hall parameter by fluctuations of arbitrary magnitude in the local electrical conductivity. The second area is concerned with achieving uniform discharges in laser gases flowing at supersonic speeds. Experimental results are presented which describe the performance of a simple double-discharge arrangement for achieving stable CW excitation in N2 and N2/CO mixtures.
