Paper Abstract

It is well known that arc plasma is one of the main tools for the ground simulation of the reentry environment, so its experimental diagnoisis is very important. We have etsablished a set of arc plasma supersonic nozzle flow device with high stability and running continuously. The stability of spectral intesnti for supersonic arc-jet is 1-1.5%. On the basis of the device we have made a spectroscopic diagnostic investigation on the supersonic nozzle flow of non-equilibrium arc plasma for argon arc-jet and obtained the rich experimental diagnostic results about supersonic arc-jet. The experiments results show that the electron temperature of supersonic arc-jet changes non-monotonically, and it decrease in a range and increases in the next range periodically along with the flow direction. The established device and diagnostic method on supersonic flow of arc plasma has a very wide application in the research on non-equilibrium flow mechanisms of high temperature gases.
