Flame characterization at two different pressures combining several PLIF channels and measurement planes. Instantaneous kerosene mole fraction (top), OH-PLIF signals and temperature (bottom) at 0.83 MPa in axial configuration (a) and in radial configuration at a position z/D = 0.75 (b), at 1.80 MPa in axial configuration (c) with an air inlet temperature of 670 K. Color coding: grey-to-white scale: OH signal; color scale (top): kerosene mole fraction; color scale (bottom): temperature; beige coloring (bottom): OH gradient.
