COMPARISON OF RESULTS OBTAINED FROM TEMPERATURE MEASUREMENT AND NUMERICAL SIMULATION OF DC PLASMA ARC

SHAO QI\|YUN HE YU\ GUO WEN\|KANG\ XU PING\ ZANG DE\|HONG (Institute of Modern Physics, Fudan University, Shanghai\ 200433) (Received 2 January 1999)  
The computational method of temperature distribution of free\|burning arc is investigated by using a numerical simulation model, which is based on the local thermodynamic equilibrium. A spectrum temperature diagnostic system of plasma torch based on charge coupled device technology is also presented. Potential, velocities and temperature distribution profile are obtained. These theoretical predictions are in fair agreement with the experimental results.  PACC: 5225; 5265; 5270
