- Abstract
Performance of Magnetohydrodynamics (MHD) accelerator with equilibrium air flow was numerically studied in this contribution. The one-dimensional numerical simulation is performed to evaluate MHD accelerator performance using the Magnetohydrodynamic Augmented Propulsion Experiment (MAPX) channel built and developed at NASA Marshall Space Flight Center. MHD accelerator performance is numerically computed using a set of differential equation with MHD approximations, which can then be solved by MacCormack scheme. Working gas of equilibrium air- plasma used in the present calculations is modeled by diatomic molecule of nitrogen and oxygen. In order to simulate seeded air flow in the channel, the potassium has been used in the model. Hydrogen is also added to the equilibrium air-plasma as an application of MHD acceleration for advanced space propulsion system.
