Minimum ignition energy of a laser-ignited single micron-sized iron particle

In this work, we develop a novel method to accurately measure the minimum ignition energy (MIE) of a micron-sized flying iron particle. A stable feeding of single iron particles is achieved using a newly developed particle supply system. Ignition is initiated by a 915 nm infrared...

Energy Policy and Energy Management in China: Governance Logic and Future Pathways of Structural Transformation

China’s energy policy and management are transitioning from scale expansion to systemic restructuring. During the 14th Five-Year Plan period (2021–2025), renewables accounted for approximately 60% of installed capacity, and the Energy Law took effect. Entering the 15th Five-Year...

Development and validation of the premixing-phase model in the three-dimensional fuel–coolant interaction code SEINA-3D

Premixing during a fuel–coolant interaction determines the three-dimensional melt–water–vapor state available to a subsequent steam explosion. This study develops and validates the premixing-phase model of the three-dimensional fuel–coolant interaction code SEINA-3D. The model ad...

Separated liquid-vapor pathways: a hybrid cooling strategy with selective surface modification and jet impingement in open microchannels for enhanced heat transfer

With the rapid development of chip technology and the ever-increasing power density of high performance devices, the demand for efficient thermal management solutions has become increasingly critical. This study demonstrates that, in flow boiling, the “separated liquid-vapor path...

Analysis of supercritical CO2 brayton cycle system for laser inertial confinement fusion concept reactors

The large temperature difference between the PbLi and S-CO 2 cooling loops in a laser inertial confinement fusion reactor complicates efficient heat recovery and can degrade the performance of a conventional single-source power-conversion system. To address this issue, this study...

Experimental study on plasma-assisted atomization characteristics of n-Dodecane sprays

In response to the global demand for low-carbon transportation, enhancing fuel combustion efficiency is essential to reducing emissions. In high-temperature and high-pressure combustion chambers, the extremely short residence time hinders effective atomization and secondary dropl...
