Numerical Study of Hybrid Plume.
Abstract
The fluid modeling of plasma-gas kinetics including momentum transfer and charge exchange reaction, the study of parametric dependence of ion cyclotron range of frequency heating efficiency, and conceptual design of the tandem mirror plasma source has been accomplished. A preliminary study was carried out by using a much simpler fluid model to investigate the feasibility of the hybrid plume concept. It was demonstrated that the exhaust duct can be protected by a supersonic gas jet from the hot plasma core. The code was expanded to include momentum transfer and recombination reaction. It was found that the ions are cooled down further at the end of the exhaust duct with the inclusion of additional physics properties. Thrust contour can now be calculated. Presently, the steady state fluid model and uniform magnetic field are assumed. In the coming year the code will be further expanded to become time dependent and to include a non-uniform magnetic field. A slab model for ion cyclotron range of frequency heating has also been developed. The parametric dependence of the loading resistance of the plasma on the antenna was analyzed. The conceptual design of the plasma rocket was obtained. The engineering design of the I sub sp plasma propulsion is in progress.
