The Influence of the Arc Current on the Energy Flows in the Arc Heater Channel
Original language description
By means of the mathematical-physical model the measurements on the experimental arc heater with argon as a working gas are investigated. The model is based on mass and energy conservation equations and Ohm?s law. The input data are experimentally obtained integral quantities of the arc current I (50 ? 200 A) and the voltage U (~100 V), the mass flow rate of working gas G (up to 22 gs-1), energy losses of the anode channel Pz, the enthalpy flow on the arc heater output and material functions of argon. Solving the set of the above mentioned equations together with the measured integral conditions, we can determine the energy flows by convection, conduction and radiation from the arc. Presented results of the investigation are temperature and velocity fields, the share of the radiation energy flow on the Joule?s losses, axial dependencies of the arc radius, of the heated zone radius and of the mass flow rate in the arc.
