Combustion instability coupling with feed system acoustics [PDF]

open access: yes
High frequency combustion instability has recently been observed by Rocketdyne in a 40K thrust methane/LOX combustion chamber. The oscillations had frequencies as high as 14,000 Hz with pressure amplitudes in the LOX dome of 500 psi at a chamber ...

Study of Temperature Gradient in Burning of Alternative Engine Fuels

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2008
The paper gives an approximate method for calculation of the temperature at a final stage of fuel-air mixture burning in a closed vessel that is a combustion chamber of the internal combustion engine (ICE).

Carbon Neutrality and Business Models: Mixed‐Method Study of Business Strategies and Decarbonization Pathways

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study adopted a mixed‐method approach to examine decarbonization business models/strategies employed across the energy ecosystem. In study 1, we conducted a systematic literature review of 94 studies to identify business models/strategies mapped to five energy ecosystem contexts—energy systems' transition, energy systems—demand side ...

Effect of structural parameters of active pre-chamber on ammonia/hydrogen premixed combustion process: A numerical investigation

open access: yesCase Studies in Thermal Engineering
The development of zero-carbon fuels is of great significance for reducing carbon emissions. Using an ammonia/hydrogen mixture as fuel, the combustion in engine through an active pre-chamber has a good effect on reducing carbon emissions.

Insight Into Puncture‐Induced Thermal Runaway in Lithium‐Ion Batteries to Reduce Fire Risks in Electric Vehicle Collisions

open access: yesBattery Energy, EarlyView.
This review examines nail penetration‐induced thermal runaway (TR) in lithium‐ion batteries, analyzing experimental and modeling studies on critical factors—battery materials, nail properties, state of charge, and penetration dynamics. It also explores internal short‐circuit modes, TR severity, and safety solutions such as advanced separators, non ...

CO2 Methanation Of Co/CeO2 Prepared by Wetness Impregnation of Co on Flame‐Synthesized CeO2

open access: yesChemCatChem, EarlyView.
Tailoring the interaction between cobalt (Co) species and flame‐synthesized cerium oxide (CeO2) influences selectivity in CO and CO2 hydrogenation. The chemical state of Co in catalysts with varying loadings was analyzed. Correlations between chemical state, particle size, and catalytic performance offer insights for designing more selective and stable
