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.
