The Flame Nebula, located about 1,400 light-years away from Earth, is a hotbed of star formation less than 1 million years ...

A balloon filled with helium and one filled with hydrogen are ignited. Hydrogen provides a loud explosion and flame. He(g) + O 2 (g) → N.R. Light the candle on the end of the yardstick and lower the ...

Firstly, careful design is needed to make hydrogen combustion stable, as hydrogen flame propagation velocity is very high — up to seven times faster than natural gas, which may lead to flame ...

The chemical reactions of hydrogen combustion occur because certain atoms and molecules are very reactive—they are unstable on their own and quickly combine with other molecules or atoms.

Say hello to hydrogen combustion. These vehicles use the same ... of reaching a higher thermal efficiency thanks to a higher flame speed than gasoline, allowing it to achieve efficiencies of ...

through the diffusion flame can be determined using a planar laser-induced fluorescence technique. These experiments will provide data to enable the validation and enhancement of chemical kinetic ...

The video provides an impression of the challenge yielding safe and stable combustion with hydrogen as fuel. Early in the video, a stable premixed hydrogen flame can be seen under typical gas turbine ...

Komatsu says it has begun testing the world’s first large dump truck powered by a hydrogen combustion engine. Details at ...

Advanced Collaboration Leads to Hydrogen Engine Breakthrough Cummins, in collaboration with key tech leaders like Johnson ...

Green hydrogen is often proposed as ... and stabilizing the flame. In turn, this reduces the temperature in the combustion chamber and produces fewer nitrogen oxides. The re-circulation of the ...

There are two basic approaches to using hydrogen in vehicles: the proton exchange membrane (PEM, also called polymer electrolyte membrane) fuel cell and the classic internal combustion engine (ICE).
