Study of a disk MHD generator for nonequilibrium plasma generator(NPG)system

摘要

Design and performance prediction studies of a disk type magnetohydrodynamic(MHD) generator which is applied to the non equilibrium plasma generator(NPG)system have been performed. The main objective of the present study was to find out whether a sufficiently high output performance Demonstration is possible with the disk generator which is planned to be used for the NPG-MHD disk Pulse power demonstration. A present numerical simulation showed that the original constant height Channel could provide not more than 20/100 of enthalpy extraction because its channel shape could not Sustain the working plasma in the stable regime against ionization instability throughout the channel.
