A numerical model is constructed for the two-dimensional flow of a three-component plasma in order to study the impurity dynamics in the channel of a magnetoplasma compressor. The plasma consists of electrons and two ion species: light ions (the bulk component) and heavy ions (the impurity). A hydrodynamic description can be used for the plasma. The calculations show that under the influence of the electromagnetic forces a mass separation of the ions takes place. Specifically, the impurity is displaced toward the cathode, and it prevents the bulk component from contracting to the channel axis. The plasma is purified with a diverter, which is an aperture in the central electrode. After the purification, the compression properties of the flow are restored. The calculations reveal the relative properties of compressional plasma flows and ion separation in channels with and without the diverter for various flow regimes.
