Abstract
|
Plasma
assisted combustion promises to improve engine performance, increase lean
burn flame stability, reduce emissions, and enhance low temperature fuel
oxidation and processing. Significant progress has been made towards the
applications of plasma in engines and the understanding of the fundamental
chemistry and dynamic processes in plasma assisted combustion via the synergetic
efforts in advanced diagnostics, combustion chemistry, flame theory, and
kinetic modeling.
New observations of plasma assisted ignition enhancement, ultra-lean combustion, cool flames, flameless combustion, and controllability of plasma discharge have been reported. Advances have occurred in the understanding of non-thermal and thermal enhancement effects, kinetic pathways of atomic O production, diagnostics of electronically and vibrationally excited species, plasma assisted combustion kinetics of sub-explosion limit ignition, plasma assisted low temperature combustion, flame regime transition of the classical ignition S-curve, dynamics of the minimum ignition energy, and the transport effect by non-equilibrium plasma discharge. These findings offer new opportunities in the development of efficient plasma discharges for practical applications and predictive, validated kinetic models and modeling tools for plasma assisted combustion at low temperature and high pressure conditions. Authors review the progress and the gap in the knowledge of plasma assisted combustion in applications, chemistry, ignition and flame dynamics, experimental methods, diagnostics, kinetic modeling, and discharge control. |
