Plasma assisted combustion is a promising technology to improve engine
performance, increase lean burn flame stability, reduce emissions, and enhance lowtemperature fuel oxidation and processing. Over the last decade, significantprogresses have been made towards the applications of plasma in engines and theunderstanding 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, andcontrollability of plasma discharge have been reported. Advances in understanding of
non-thermal and thermal enhancement effects, kinetic pathways of atomic O
production, diagnostics of electronically and vibrationally excited species, plasma
combustion kinetics of sub-explosion limit ignition, plasma assisted low temperature
combustion, flame regime transition of the classical ignition S-curve, dynamics of theminimum ignition energy, and the transport effect by non-equilibrium plasma
discharge. These findings and advances have provided new opportunities in thedevelopment 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.
This article is to provide a comprehensive overview of the progress and the gap ofknowledge of plasma assisted combustion in applications, chemistry, ignition andflame dynamics, experimental methods, diagnostics, kinetic modeling, and discharge
control.
Professor Yiguang Ju is a Robert Porter Patterson Professor at Princeton University. His bachelor degree inEngineering Thermophyiscs from Tsinghua University in 1986, and his PhD degree in Mechanical andAerospace Engineering from Tohoku University in 1994. He was appointed as an Assistant and Associate
Professor at Tohoku University in 1995 and 1998, and as a Changjiang Professor and the Director ofThermophysics Institute at Tsinghua University in 2000. He joined Princeton University in 2001 and became afull professor in 2011. He received a number of awards including the Distinguished Paper Award from the Thirtythird International Symposium on Combustion (2010), the NASA Director’s Certificate of Appreciation award(2011), the Friedrich Wilhelm Bessel Research Award by the Alexander von Humboldt Foundation (2011), andthe Robert Porter Patterson Professor of Princeton University (2013).
