OH PLIF image collection

Freestream conditions:
M = 2.4
p = 40 kPa
T = 1500 K

Injection:
Hydrogen is injected perpendicularly to the crossflow on a flat plate from a contoured nozzle injector. Injection is sonic. The injector has a diameter D = 2 mm and it is located about 65 mm downstream of the leading edge of the plate. A schematic diagram of the injector is shown in the following figure.

Coordinate system:
x - stream-wise direction
y - wall-normal direction
z - span-wise direction

Comments:
The coordinate axis have been normalized by the jet diameter. Consistent image corrections (background subtraction, laser sheet correction and dewarping) and colormap have been applied to all cases in order to approximately reconstruct the relative intensity of each case.

Case J = 0.27
z/d = 0

z/d = 5

Case J = 0.68
z/d = 0

z/d = 5

Case J = 1.77
z/d = 0

z/d = 5
