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 60° (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.[PUBLICATION ABSTRACT]
