Abstract

An arc-heated plasma wind tunnel with power of 0.4 MW has been constructed at Chonbuk National University (CBNU) in Korea. A segmented arc plasma torch was adopted as the plasma source and was designed to produce a supersonic plasma flow with enthalpy greater than 270 kJ/mol at a velocity of Mach 3. The characteristics of the plasma flow were investigated for gas flow rates ranging from 5 × 10⁵ to 8 × 10⁵ sccm and input current ranging from 200 to 350 A. The facility is capable of producing ion flux greater than 10²⁴ m^-2 s^-1, as well as heat flux greater than 10 MW/m², levels that are relevant for the study of plasma material interactions under fusion reactor conditions.
