Investigation Of The Ionization Of Helium-cesium Mixture With Turbulent Flow

llhe ionization of a Helium-Cesium mixtuze in turbulent flow is investigated. A high level of ionization of the Cesium seed in the mixture is achieved by an A C dischatge, instad of the thed equilibrium combustion ionization, thus eliminating the reduction of Performance of a MHD generator due to the flow of combustion products through the generator. Calculations are pdormd, using two particle balance equations for the electrons and excited state in the plasma and an electron energy equation. The effect of vwing the mixture velocity and Cesium seed fraction on the discharge parameters is examined. Results show that for an electrvn density range of 1019-1#1 mm3 the electron temperature ranges between 2300-3100 K, the electric field 4500-7500 (V/m), the current density 104-1 06 (A/m2), and electrical conductiviity 20-140 (hhodm).
