Cool Flames Investigation (CFI) Cool flames are a very unique chemical phenomenon that can occur when many hydrocarbons and related fuels are heated in the presence of air. Cool flames are especially unique in that their chemical reaction rate first increases and then decreases with increasing temperature; this is somewhat counterintuitive and means that these … Read the rest ⇢
Flame Extinguishment Experiment (FLEX) The Flame Extinguishment Experiment (FLEX) experiment was designed to assess and quantify the effectiveness of inert-gas suppressants in microgravity and obtain the most conservative estimate of the limiting oxygen index for steady combustion. FLEX is studying the behavior of near-limit diffusion flames examining in detail liquid- and gas-phase transport and chemical … Read the rest ⇢
Flame Extinguishment Experiment-2 (FLEX-2) The second in the FLEX series of experiments, the FLEX-2 investigation uses fuels and environmental conditions that mimic real combustor conditions. The investigation will extend and advance the research into droplet combustion, studying the influence of sub-buoyant convective flows on combustion rates, determining the influence of a second burning droplet on … Read the rest ⇢
Flame Extinguishment Experiment -2 JAXA (FLEX-2J) The FLEX-2J experiment is a joint effort between NASA and the Japanese Space Agency, JAXA, as well as Nihon University and Yamaguchi University. Derived from the JAXA Group Combustion Experiment science objectives, the FLEX-2J will complement those goals using the NASA FLEX-2 hardware and combustion facilities on ISS. FLEX-2J … Read the rest ⇢
FLEX-Italian Combustion Experiment for Green Air (FLEX-ICE-GA) The FLEX-Italian Combustion Experiment for Green Air will test surrogate fuels as defined by the Italian Space Agency (ASI) within the CIR in the FLEX-2 configuration. A collaborative agreement between U.S. and Italian scientists from the Italian National Research Council–Istituto Motori will allow collaboration on research into biologically … Read the rest ⇢
