Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Laser ignition of methane jets in homogenous and isotropic turbulence
The ignition of a pulsed methane jet by a laser-induced spark was investigated in air under the influence of homogenous and isotropic turbulence with zero mean flow. In this way, the contribution of the turbulent velocity fluctuations of the environment can be isolated from the mean flow component.

Unveiling Localized Heat in Lithium‐Ion Cells for Intelligent Temperature Sensing
Heat generation, thermal responses, and intelligent management in batteries. Lithium‐ion batteries (LIBs) power electric vehicles, portable electronics, and grid‐scale storage, yet their safety, performance, and lifetime are constrained by thermal effects.

Results of 1/4-Scale Experiments. Vapor Simulant And Liquid Jet A Tests [PDF]
A quarter-scale engineering model of the center wing tank (CWT) of a 747-100 was constructed. This engineering model replicated the compartmentalization, passageways, and venting to the atmosphere.

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

The role of chemistry in the oscillating combustion of hydrocarbons : an experimental and theoretical study [PDF]
The stable operation of low-temperature combustion processes is an open challenge, due to the presence of undesired deviations from steady-state conditions: among them, oscillatory behaviors have been raising significant interest.

ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the
