In the field of fire safety, the propagation prediction of a flame along a solid vertical wall requires radiation quantification. The thesis objective is to quantify and characterize the PMMA flame soot. Gaseous burner steady flame will also be studied. The LII optical method, after calibration (extinction), provides 2D volume fraction fields and the combustion rate in function of the height for the PMMA flame. Then, the soot aggregate morphology is determined by TEM images and size distribution measurements. The optical properties are obtained with in-situ and ex-situ measurements (temperature effect) of the spectral extinction, coupled with a mass concentration measurement to obtain the index function. This database will allow the prospect to calculate the soot radiation and to use it in a propagation model.
