Abstract:

To explore the application of the magneto-hydrodynamic technology to fields such as hypersonic vehicles and exploitation of wave energy, nuclear energy and solar energy, we establish an experimental MHD system, introducing its composition, design, and test results. An MHD channel with a supersonic nozzle of Ma=1.5 is developed, with the electrical conductivity in the channel reaching 14 S/m in an average of 9 S/m when the power of the plasma torch is 120 kW. Theoretical calculation indicates that with the electrical conductivity of 9 S/m, the output power of the MHD channel could reach 1 872.96 W for a single electrode and 5 993.47 W for the whole channel. The experimental results show that the experimental MHD system based on the plasma torch is capable of the ground-experiments for MHD power generation, MHD acceleration and MHD flow control.
