• We studied mixing of impinging radially injected gas jets and main crossflow.
• Axial and radial temperature profiles were measured above jets injection plane.
• Dependence is proposed to calculate the depth of penetration of counter flow jet.
• Counter flow penetration depth and radial penetration depth are linearly related.
Experimental investigation and numerical calculation of the macromixing of multi-orifice impinging radial jets and main crossflow in the plasma-chemical reactor channel were performed. The emphasis is on the analysis of the conditions providing the formation of a jet on the channel axis directed toward the main flow. Axial and radial distributions of the temperatures were measured in four channel cross sections above the jets injection point. An empirical dependence is proposed to calculate the axial depth of penetration the counter flow jet. The dependence generalizes the measurement results and is in agreement with the data of other authors. The relationship between the parameter of counter flow jet penetration depth and the parameter of impinging jets radial depth of penetration was revealed. Experimental data are in qualitative agreement with the numerical simulation results.
