Like much in life, the difference between detonation and pre-ignition, and their effects, comes down to timing. Both refer to a situation when an engine's fuel/air mixture combusts at the wrong time, ...

Detonation combustion achieves near-constant-volume burning, drastically reducing entropy generation and wasting less energy as heat compared to traditional deflagration propulsion. Its supersonic ...

Suddenly, there's a flash of intense light and heat, followed by a rapidly expanding fireball. Combustion of high explosives is everywhere in popular culture, and it's also critical for ensuring the ...

Scientists analyzed detonation formation in hydrogen/methane air mixtures, quantifying the effect of non-thermal reactions on the mechanism of detonation Small-displacement turbocharged internal ...

This summary provides an elucidation of the complex processes underlying flame acceleration and the subsequent transition to detonation in combustion systems. Flame acceleration, a phenomenon in which ...

Over the years [Integza] has blown up or melted many types of jet engine, including the humble pulsejet. Earlier improvements revolved around pumping in more fuel, or forced air intakes, but now it’s ...

The bright minds from the University of Central Florida (UCF) are on a path to revolutionize the future of air travel, and even facilitate interplanetary transportation. In the quest to find a ...

UCF researchers say they've trapped a sustained explosive detonation, fixed in place, for the first time, channeling its enormous power into thrust in a new oblique wave detonation engine that could ...

When your car starts making a metallic knocking sound under the hood, you'd assume it could only be one thing: the engine. However, there are two common culprits, and they're definitely not the same.
