USMP-4 MGBX ELF, Doi and Lindsey with glovebox experiment

STS087-330-009 (19 November – 5 December 1997) --- Astronauts Takao Doi (left) and Steven W. Lindsey check out the Enclosed Laminar Flames (ELF) experiment on the mid-deck of the Earth-orbiting Space Shuttle Columbia. ELF has been designed to examine the effect of different air flow velocities on the stability of laminar (non-turbulent) flames. Enclosed laminar flames are commonly found in combustion systems such as power plant and gas turbine combustors, and jet engine afterburners. It is hoped that results of this investigation may help to optimize the performance of industrial combustors, including pollutant emissions and heat transfer. The microgravity environment of space makes a perfect setting for a laboratory involving combustion, an activity that creates convection in normal gravity. In microgravity, scientists can study subtle processes ordinarily masked by the effects of gravity. Doi is an international mission specialist representing Japan's National Space Development Agency (NASDA) and Lindsey is the pilot. Both are alumni of NASA's 1995 class of Astronaut Candidates (ASCAN).
