Experimental Investigation of Radiation Emitted by Optically Thin to Optically Thick Wildland Flames

Figure 2

Emitted radiation from flames generated by the burning of the 1 m long WS fuel bed. (a) Spectral intensity versus wavenumber (and wavelength) obtained from successive acquisitions and (b) intensity integrated over wavenumber versus time. Solid and dotted black lines correspond to blackbody emission curves at temperatures of 1400 K and 1600 K. The fuel load is 1 kg/m².
