Fluid-mechanical structure of methane-air and propane-air turbulent premixed flames

Nihon Kikai Gakkai ronbunshu, 2015
The flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic of turbulence have been closely examined by using a three-color six-beam LDV system.

Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

Advanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Towards detailed combustion characteristics and linear stability analysis of premixed ammonia‒hydrogen‒air mixtures

Applications in Energy and Combustion Science
In this study, premixed ammonia‒hydrogen‒air mixtures at different pressures (50∼300 kPa), equivalence ratios (0.7∼1.5), and hydrogen concentrations (9∼50.00 %) were centrally ignited in a closed vessel, and the propagation of a spherical flame was ...

Multicomponent Fuel Diffusion Flames: Flame Structure for Coupled Diffusion-Flame and Premixed-Flame Burning Regimes

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
The analysis addresses some aspects of the extinction and the structure of diusion flames established by burning of two fuels. This analysis is asymptotically performed presuming one-global-step chemical reactions with large activation energies. By working with fuels with dierent activation energies, the structure is composed by two zones with dierent ...
