As part of an experiment assessing combustion and fire suppressants in space, a 3-millimetre-wide drop of heptane fuel was ignited and filmed as it transformed into soot. A bright backlight ...

Tiny droplets of fuel, like methanol or heptane, are dispensed into the combustion zone through a syringe. “Since there is no gravity, the droplet just sits there,” Williams says.

Le Chatelier discovered three stages of combustion; ... have found that for heptane-air mixtures the ignition temperature is only changed some 8° C. when the heptane-to-air ratio is increased ...

Now, the scientists want to get the right mix of fuels to generate the same combustion on Earth, with a special project called the Cool Flame Investigation (such name) starting next winter.

Astronauts typically try to avoid starting fires in space, but new research on the behavior of flames in orbit could have benefits closer to home.

SAE Transactions, Vol. 116, Section 3: JOURNAL OF ENGINES (2007), pp. 1398-1408 (11 pages) The effects of variable compression ratio (CR) and fuel composition on thermal efficiency were investigated ...

FLEX-ible insight into flame behavior Date: November 30, 2011 Source: NASA Summary: Whether free-burning or smoldering, uncontrolled fire can threaten life and destroy property.

Combustion of the mixture of 25 volume percent ç-heptane in toluene reveals interesting information, compared to emissions from pure toluene: concentrations of ethylbenzene, styrene, and ...

All gasoline is a brew of many different hydrocarbon molecules, ranging from heptane to decane and beyond. The hydrocarbon clearly identified on the pump—and the one many consumers associate ...

The remaining percentage (5% and 2%, respectively) consists of heptane. What’s the difference between 95 and 98 gasoline? Premium 98 gasoline is more resistant to combustion than regular 95.
