This thesis reports the results of an experimental study on the combustion of isolated droplets of isopropanol for ambient pressures of 1 bar, 5 bar, and 10 bar, with buoyancy-induced flows providing a convective flow around the burning droplets. Isopropanol was chosen as a fuel because it can be produced in large quantities from various biomass feedstocks. Also, the burning characteristics of isopropanol under different ambient pressures hasn’t been explored in great detail. In this study, isopropanol droplets were mounted on two 14μm SiC fibers and ignited electrically by heated coils that served as an ignition source. The droplet burning history was recorded using two cameras: a black and white (BW) camera to record images of the droplet; and a color camera that captured the flame structure. The purpose of the study was to observe how ambient pressure affected burning, including the evolution of droplet and flame shape, and sooting characteristics as pressure was increased.Results from the experiments showed that as pressure was increased, the burning rate of the droplet also increased. Flames were observed to be more stretched in the order of 10 bar > 5 bar > 1 bar which is attributed to the increased levels of convection. Sooting dynamics were manifested by flame luminosity with trends showing that an increase in ambient pressure increased sooting. A correlation of the experimental data for the isopropanol burning rate in a convective environment versus a reduced gravity environment in terms of ambient pressure is also proposed.
