DescriptionThe effect of low pressure on the behavior of fires is very important to the study of fire safety in the aviation industry. This thesis explores the effect of low pressure on different components of flammability at low pressures, like those encountered at high altitude. An experiment was setup to measure the time to ignition, the mass flux at ignition, as well as the steady burning mass flux for different pressures and oxygen concentrations. The test measured the mass loss, oxygen consumption, soot production and average flame temperature. A square sample of PMMA was burned under different external heat fluxes, total pressures and oxygen concentrations. The experiments were compared to analytical expressions, to try to understand how pressure and oxygen concentration affect the behavior of a fire. Low pressure environment reduced the ignition delay time, indicating a sample is more prone to ignition at lower pressure. On the other hand the sample showed a reduction of steady burning mass flux, indicating the fire is less intense at lower pressure. The results show a good agreement with the analytical analysis
