Magnetizing Force

The possibility of oxygen separation/enrichment from atmospheric air using a magnetizing force was investigated numerically. Direct Simulation Monte Carlo (DSMC) method was utilized to obtain distribution of oxygen concentration in a capsule under a strong magnetic field gradient. The molecular movement was calculated by taking into account the magnetizing force on the molecules. The computations were performed for a wide range of pressure and magnetic flux density gradient. The simulation results showed that there is a possibility of oxygen separation/enrichment from atmospheric air under a strong magnetic field gradient.

Magnetizing Force

Oxygen is a paramagnetic gas and it has relatively high magnetic susceptibility. On the contrary, nitrogen is a diamagnetic gas and it has relatively low and negative magnetic susceptibility. This results in countermagnetizing forces acting on these gases. The characteristics of oxygen separation/enrichment from atmospheric air in a capsule and air flow in a parallel-plate duct using a magnetizing force were investigated numerically. The direct simulation Monte Carlo (DSMC) method was utilized to obtain distribution of oxygen concentration of air under a strong magnetic field gradient. The molecular movement was calculated by taking into account the magnetizing forces on the molecules. The computations were performed for a wide range of pressure and magnetic flux density gradient. Quantitative characteristics of oxygen separation/enrichment from atmospheric air under a strong magnetic field gradient and a parameter which governs this phenomenon are obtained from the simulation results.

The molecular movement was calculated by taking into account the magnetizing forces on the molecules. The computations were performed for a wide range of pressure and magnetic flux density gradient. The simulation results showed that there is a possibility of oxygen separation/enrichment from decompressed air under a strong magnetic field gradient.
