- Abstract
- An experimental program was conducted to study the burning of laminar gas-jet diffusion flames in a zero-gravity environment. The tests were conducted in the Lewis Research Center's 2.2-sec zero-gravity facility. The photographic results indicate that a sudden decrease in gravity level from one to zero effected an immediate reduction in the length of the flame. Continued time in zero gravity resulted in the flame expanding away from the burner. For lower Reynolds number fuel flows, the flames increased in size until they appeared to be extinguished, while for high Reynolds number fuel flows they established a steady-state zero-gravity configuration.
