Book Description
Microgravity droplet combustion experiments were performed in atmospheres with elevatedconcentrations of CO2 at pressures of 1.0 atm, 3.0 atm, and 5.0 atm to examine theeffects of a radiatively participating gas commonly used as a fire suppressant in space applications.Results were obtained from two unique experimental platforms, NASA GlennResearch Center’s 5.2 second drop tower (i.e., the Zero Gravity Facility “ZGF”) and theInternational Space Station (ISS). Tests performed in the ZGF deployed methanol andn-heptane droplets, with initial diameters ranging from 1.25 mm to 2.0 mm, onto a 120micron quartz fiber. Tests performed on the ISS deployed n-heptane droplets with initialdiameters ranging from 2.0 mm to 4.0 mm and were were either freely deployed or tetheredwith an 80 micron SiC fiber. Ambient atmospheres comprised 21% O2 with variousconcentrations of CO2 ranging from 0% to a maximum of 70% by volume with a balanceof N2 . Results are reported showing the effects of a thermally participating gas atatmospheric and elevated pressures on the fuel droplet’s average burning rates, sootingpropensity and, in the case of methanol at 1 atm, on its unique extinction mechanism.

Book Description
A Gallery of Combustion and Fire is the first book to provide a graphical perspective of the extremely visual phenomenon of combustion in full color. It is designed primarily to be used in parallel with, and supplement existing combustion textbooks that are usually in black and white, making it a challenge to visualize such a graphic phenomenon. Each image includes a description of how it was generated, which is detailed enough for the expert but simple enough for the novice. Processes range from small scale academic flames up to full scale industrial flames under a wide range of conditions such as low and normal gravity, atmospheric to high pressures, actual and simulated flames, and controlled and uncontrolled flames. Containing over 500 color images, with over 230 contributors from over 75 organizations, this volume is a valuable asset for experts and novices alike.
