| Abstract: | In order to explore the structure and reaction behavior of the combustion zone propagating through PMMA particle cloud, the direct emission of flame and laser light scattering images of the particles were recorded by CCD and high speed video camera. The temperature profile of the combustion zone was measured by micro thermocouple, the reaction behavior of PMMA particles in the combustion zone was studied by the ion current during the combustion zone propagating through PMMA particle cloud. |
