Numerical Simulation in Nonequilibrium Disk MHD Generators Considering Fluctuation of Seed Fractioin

摘要

Fluctuation of plasma properties in nonequilibrium disk MHD generators and its effects on generator characteristics are discussed by numerical simulation, taking account of the fluctuation of seed fraction at the inlet of the generators. Effective electrical conductivity and effective Hall parameter are reduced due to the fluctuation of plasma properties when the partially ionized seed appears.
