Microgravity platforms are valuable research tools for improving our understanding of the complex processes of soot formation and oxidation. The absence of buoyancy-induced flows means that the boundary conditions of experiments and related numerical models can be controlled and better defined. In order to measure the relevant parameters of soot particles advanced diagnostic methods are required; laser-induced incandescence techniques have been successfully implemented in drop-tower and parabolic flight campaigns. It is now possible to obtain full-field images of soot characteristics in laminar diffusion flames under microgravity. The results demonstrate that the characteristics of soot formation and oxidation are indeed drastically altered under microgravity, resulting, for example, in an appoximate doubling of primary particle sizes. These experimental findings are being used to develop and refine soot models that will finally enable a reliable and comprehensive description of soot evolution in combustion systems.
