| Abstract: | The paper presents the results of experimental investigations of aerodynamics and heat transfer in a vortex plasma reactor with gas jet injection along its axis. The process of mixing under quasi-isothermal conditions (injection of slightly heated jet) and inhomogeneous conditions (injection of helium and argon) as well as with the injection along the axis of plasma jet is studied consistently. A detailed comparison of temperature fields and concentrations is presented for these conditions. The process of jet expansion is shown to be defined mainly by three factors — centrifugal mass forces, buoyancy forces and initial velocity shift in a jet at the chamber inlet. The end flows contribute considerably to the process of jet mass transfer with peripheral flow. |
