Nonequillibrium Effective Conductivity of a Seeded Noble Gas Flowing in a Magnetic Field

A method to compute the effective conductivity of argon, seeded with K (flowing in a magnetic field has been worked out with segmented electrodes) as a function of pressure and temperature of the gas and the induced electric field (KVB); the duct is assumed to have segmented electrodes. It is seen that for a given (KVB), the dependence of the effective conductivity on pressure and temperature of the gas is empirically given by a close fitting power law. Such a relation will considerably simplify the analysis of the flow of a seeded gas in a magnetic field. In contrast to earlier analyses, based on the phenomenological theory, this paper is based on the expressions, obtained from the solution of Boltzmann's transfer equation. The computations correspond to the optimum seeding ratio of 0.02 for maximum conductivity.
