Abstract Local soot concentrations in non-buoyant laminar diffusion flames have been demonstrated to be the outcome of two competitive processes, formation and oxidation. It was first believed that controlling mechanism thus volume fractions could scaled with a global residence time. Later studies showed this is not necessarily case local ratio oxidation times prime variable ultimate fractions. This strong function geometry flow field, very difficult properly quantify. study presents series...
Fuel is injected through a porous flat plate perpendicular to stream of oxidizer flowing parallel the surface burner for regimes corresponding fire scenario in spacecrafts. Particle image velocimetry used characterize flow structure nonreactive conditions. The influence fuel injection on evaluated, and detailed description presented. For combustion experiments, minimum velocity shown be necessary stable flame. thermal expansion flame evaluated. A complementary numerical study support...
A systematic numerical study of a low Reynolds number laminar diffusion flame is presented. The configuration used that boundary layer flow established over flat plate burner. importance this relies on its potential use for the assessment flammability materials to be in space vehicles. focuses validity formulations these flames. characteristic velocities are representative microgravity environments [O(100 mm/s)]. Parietal injection results eventually separation establishing two regimes:...
Une étude numérique est effectuée sur des brûleurs poreux qui simulent la combustion d'un combustible solide ou liquide. L'air et un mélange contenant 30 % d'O2 70 N2 sont utilisés comme oxydant à vitesses d'injection de 2,7 4 cm.s-1 correspondant aux systèmes conditionnement d'air vaisseaux spatiaux. Le système équations Navier-Stokes conservation espèces résolu par simulation directe. L'approche centrée l'influence du champ gravitationnel géométrie flamme, les limites d'extinction le...
