NUMERICAL MODELING OF THE THERMAL AND GASDYNAMIC STRUCTURE OF PLASMA FLOWS IN ELECTRIC-ARC REACTORS WITH THREE-JET MIXING CHAMBERS
L. I. Krasovskaya and M. A. Brich UDC 533.915:001.573 On the basis of a three-dimensional mixing model of plasma jets, a numerical study is made of the gasdynamic and thermal structure of plasma flows in three-jet mixing chambers of several types and in cylindrical reactors with such chambers. It is shown that in cylindrical chambers (with a diameter of 5-10 cm) and in a conic chamber with an apex angle of 60o (with a base diameter of 10 cm) for diameters of plasmatron nozzles of 1-2 cm the mixing of plasma jets proceeds virtually completely in the chamber volume. Application of such chambers provides the formation of rather uniform (in cross sections) temperature fields in the channels of plasma reactors. Academic Scientific Complex "A. V.
