Abstract

In this paper, a method, using the spectrum tomography combining with the principle of numerical calculation to rebuild two-temperature of plasma flow, is proposed. Heavy particle temperature of plasma flow is reconstructed based on numerical calculation and the electron temperature measured in experiment using the method. It is not the same as traditional one that reconstructs electron temperature and heavy particle temperature of plasma flow by calculating iteratively electron and heavy particle energy transfer equations with pure numerical simulation. The spatial distribution characteristics about electron temperature and heavy particle temperature of plasma flow and the factors that influence local-temperature equilibrium(LTE) are completely analyzed .In the diagnostic process, as is shown that the method omits multifarious boundary conditions and it is more feasible than that of pure numerical simulation for those plasma flows of which boundary conditions are difficult to confirm.
