| Research Abstract |
Application of 3.39μm Infrared laser absorption method for measurement of fuel vapor concentration to microgravity experiments was performed, toward clarification of the effects of fuel vapor concentration distribution around droplets on flame spread characteristics between partially prevaporized droplets. By scanning the laser path along the axis of the array in 500K air after 1.2s prevaporization, qualitative measurement of fuel vapor concentration distribution along the axis was successfully achieved, for n-decane droplet array with 1mm drolet diameter.
