Computational Magnetohydrodynamic Model of a Nonuniform Gasdynamic Mirror Propulsion System

چکیده
Parametric engineering models of the gas dynamic mirror (GDM) fusion propulsion systems[1, 2, 3, 4] have produced potentially feasible systems. However, these systems are extremely large and massive due to neutron or bremsstrahlung radiation losses for traditional and advanced fusion fuels, respectively. In order to explore designs beyond the simple uniform GDM represented by the parametric model, a 3-D complex geometry ideal magnetohydrodynamic (MHD) modeling tool[5] based on finite volume methods and adaptive Cartesian grids was developed. The explicit nature of the algorithm combined with the near relativistic magneto-acoustic wave speeds limited the utility of the model. Presented here is a new MHD implicit alorithm with embedded magnetic fields which is capable of modeling complex, nonuniform GDMs.

A Field-Reversed Gasdynamic Mirror Fusion Propulsion System
Previous studies have shown that the gasdynamic mirror (GDM) fusion propulsion system is capable of producing specific impulses in excess of 10 seconds and thrusts in the tens of kilonewtons. These propulsive capabilities arise from the ability of this magnetic fusion system to confine a hot plasma long enough to produce fusion energy while allowing a certain fraction of its charged particle po...
متن کاملMagnetic Configuration of a Reduced- Mtiss Gasdynamic Mirror Fusion Propulsion System
The gasdynamic Mirror (GDM) Fusion Propulsion System is a simple mirror magnetic confinement machine in which the ion-ion collision mean free path is significantly shorter than the length of the device. Under these conditions the plasma behaves like a fluid and is governed by gasdynamic laws which show the confimement time to vary directly with the plasma mirror ration and inversely with the pl...

متن کاملField Asymmetry and Thrust Control in the GDM Fusion Propulsion System
[Abstract] One of the notable attributes of the Gasdynamic Mirror (GDM) fusion propulsion system is the fact that it lends itself readily to thrust control due to asymmetry in the magnetic field configuration. GDM is a magnetic plasma confinement device that has been proposed as a potential propulsion system. It differs from the standard “collisionless” mirror in that it operates at a much high...
