Analysis of a Candle Flame in Microgravity

Ohio Northern University

Analysis of a Candle Flame in Microgravity examines a significant phenomenon of combustion. In normal gravity, buoyant convection is present which carries hot products upward and creates a flow of fresh oxygen to the flame. In a microgravity environment, the buoyancy effects are minimal and cause the flame to behave differently. Also, in response to g-variation, the flame experiences g-jitter effects. The test objectives of this experiment are to determine the effects of microgravity on the flame shape, color, and burning rate as they relate to the effects of g-jitter. By comparing the data collected from the apparatus being bolted to the floor grid of the aircraft to that where the apparatus free-floats, the test objectives will be achieved. We hope that our findings will provide a strong basis for future research in g-jitter effects in low gravity environments.

An outreach program is an important aspect of our project, and has been designed to interest students in the science and engineering fields. With Russ Albertson, a photo-journalist and currently a Captain on the MD-80, as our journalist, we hope to attract interest from the scientific and media worlds. COSI, Center of Science and Industry in Columbus, Ohio, is designing a small carry-on chemistry experiment for us to perform. The project will be to determine whether or not mineral oil and colored water will mix in microgravity. COSI will then use this experiment as part of their traveling outreach program and have students perform the same procedure and compare their results to ours. We will also be participating in the BP Scientists in the Classroom and BP Summer Science Camp for Kids. Lastly, we will be submitting our findings along with photos to the AIAA (American Institute of Aeronautics and Astronautics) to be published in the AIAA Student Journal.
