(a) Experimental setup for TALIF measurement and (b) image of the discharge.
Magnitude of velocity (color map) and mole fraction of air (white contour lines) predicted by the model at (a) 0.5 and (b) 1.0 SLPM.
Calibrated scans of ground state atomic oxygen at (a) 0.5 and (b) 1.0 SLPM. The two white lines show the inner and outer diameter of the glass tube.
Calibrated density distributions of ground state atomic oxygen (symbols) and predicted molecular oxygen from the model (lines). The triangles and dashed line are at 0.5 SLPM. The circles and solid line are at 1.0 SLPM. The axis for the molecular oxygen corresponds to the radial direction at 0.2 mm from the surface in Fig. 2.
