Its typical operating parameters are current up to 220 amperes, voltage about 100 volts, and argon flow rate up to 22 grams per second. Numerous experiments were carried out and many sets of integral quantities were measured. The measured data, including the arc current I, the arc voltage U, the flow rate of the working gas G, and the energy loss of the arc heater channel Pz, served as the input data of a mathematical-physical model describing phenomena inside the arc heater channel. The analysis of measured and computed data has proved radiation to be the main mechanism of radial energy transfer from the arc to the channel wall. The obtained temperature dependency of the specific radiation coefficient of argon is given in figures and compared with theoretically computed data.
