LLE Review, Volume 135 173 Introduction Fast-electron generation in laser–plasma interactions has long been of interest for a variety of reasons, such as avoiding preheat during compression in inertial confinement fusion (ICF), heating the compressed core of an ICF target for fast ignition,1 generating a shock in an ICF target for shock ignition,2 and as a means to produce energetic secondary p...

In recent years, many different plans have been considered to use the nuclear energy gained from inertial confinement fusion (ICF) as attempts to obtain high energy efficiencies. In conventional ICF methods, a small amount (about mg) of the deuterium–tritium compound is confined in a small spherical chamber of a few millimeters in radius and compressed by laser or heavy ion beams with powers in...

Low-temperature combustion modes have attracted global attention in recent years, especially the homogeneous charge compression ignition (HCCI) mode. The HCCI produces high-speed combustion, achieving relatively high thermal efficiencies while emitting low NOX and soot. However, due to lack of direct control start one main challenges this type engine is ensure that auto-ignition occurs close to...

Catalytic ignition of CH4, CO, and H2 oxidation on platinum and palladium at atmospheric pressure is studied numerically. Two simple configurations are simulated: the stagnation flow field over a catalytically active foil and a chemical reactor with a catalytically active wire inside. The simulation includes detailed reaction mechanisms for the gas phase and for the surface. The gas-phase trans...

This study investigates the effects of intermediate temperature heat release (ITHR) on autoignition reactivity full boiling range gasolines with different octane sensitivity through intake and simulated exhaust gas recirculation (EGR) sweeps in a homogenous charge compression ignition (HCCI) engine. To isolate ITHR effects, low was suppressed use high oxygen mole fraction. For quantification IT...
