Abstract
Fuel is injected through a porous flat plate perpendicular to a stream of oxidizer flowing parallel to the surface of the burner for regimes corresponding to a fire scenario in spacecrafts. Particle image velocimetry is used to characterize the flow structure in nonreactive conditions. The influence of fuel injection on the flow structure is evaluated, and a detailed description of the flow structure is presented. For combustion experiments, a minimum fuel injection velocity is shown to be necessary for a stable flame. The influence of thermal expansion on the flame is evaluated. A complementary numerical study is used to support the preceding experimental observations.
