An Experimental Study on the Effects of Pre-Chamber Geometry on the Combustion Characteristics of Ammonia/Air Mixtures Using Turbulent Jet-Post Spark Ignition Strategy

Energies
As a carbon-free fuel, ammonia faces challenges in engine applications due to its low flame propagation speed and high ignition energy. The pre-chamber turbulent jet-post spark ignition strategy (TJ-PSI) has been proven effective in accelerating the ...

Burn Selection: How Fire Injury Shaped Human Evolution

BioEssays, Volume 48, Issue 2, February 2026.
Intentional fire use exposed humans and their ancestors to high‐temperature burn injury, a risk rare in other species, bringing major survival benefits and technologies but also repeated exposure to extreme heat. The Burn Selection Hypothesis reframes this cost of fire mastery as a unique selective pressure, which shaped our evolution.

Performance Evaluation of Rice Bran Oil—Waste Cooking Oil Binary Blend‐Based Biodiesel With Normal Diesel in CI Engine

Engineering Reports, Volume 8, Issue 2, February 2026.
This study evaluates the performance and emissions of CI engines using biodiesel blends derived from rice bran and waste cooking oil, revealing that a 30% biodiesel blend significantly reduces emissions, while a 70% blend affects specific engine parameters. ABSTRACT This research investigates the performance, combustion, and emission characteristics of

Initiation of the detonation in the gravitationally confined detonation model of Type Ia supernovae

, 2009
We study the initiation of the detonation in the gravitationally confined detonation (GCD) model of Type Ia supernovae (SNe Ia). Initiation of the detonation occurs spontaneously in a region where the length scale of the temperature gradient extending ...

Estimation of the GCV of Coal Using Real‐Time Plant Data

Energy Science &Engineering, Volume 14, Issue 2, Page 905-915, February 2026.
ABSTRACT Online or real‐time strategies of estimating the gross calorific value (GCV) of coal are still not fully explored in academic literature, even though both conventional and sophisticated offline methods for estimating the GCV are well described.

Characteristics of H2/air annular jet flames using multiple shear coaxial injectors

Journal of Fluid Science and Technology, 2014
The heat transfer characteristics for the process tubes of a cracking furnace and the combustion chamber wall of a liquid oxygen/gas hydrogen rocket engine, both of which use multiple nozzles, are very important in terms of performance and safety.
