The 1st International Workshop on Near Limit Flames will be held on July 29-30, 2017 at at Boston University Photonic Center in Boston, Massachusetts, USA, before the 26th International Colloquium on the Dynamics of Explosions and Reactive Systems (ICDERS 2017).



To meet the goals of the Paris Agreement, limiting global warming to 2C above pre-industrial levels, CO2 emissions from combustion power generation need to be reduced. Biofuels and advanced engine technologies such as supercritical combustion, low temperature combustion, oxyfuel combustion, pressure gain combustion, microscale combustion, and plasma assisted combustion have great potential to improve combustion efficiency and reduction emissions. The drastic changes in fuels and the extreme engine operation conditions will significantly change the flame regimes and dynamics at near limit conditions. As such, it is necessary to advance fundamental understanding of near limit flame dynamics at extreme conditions for co-optimization of engine and fuel design.

The workshop aims to discuss the recent progress and challenges and to formulating future collaborations in theoretical, computational, and experimental studies of near limit flame dynamics in the areas such as,

*Combustion instability

*Engine knocking and detonation

*Fires and explosion

*High pressure and supercritical combustion

*Low temperature combustion and cool flames

*Microscale combustion

*Oxyfuel combustion and new combustion technologies

*Plasma assisted combustion


Topics and Sessions


At each workshop, the scientific committee will select a few topics to identify what are the important applications and technical issues, what we know, and what we do not know. Each workshop session will include an invited lecture to give a broad overview of the field and potential applications, a few position lectures to present the recent progresses and challenges, and additional highlight talks to highlight interesting findings and results given by volunteering speakers. A parallel discussion session will also be organized to discuss what need to be done and how to collaborate. The 2017 workshop topics/sessions and coordinators are:


Topic 1. Cool flames

(Coordinators, Nabiha Chaumeix and Yiguang Ju)


Topic 2. High pressure flames and diagnostics at engine conditions

(Coordinators, Isaac Boxx and William L. Roberts)


Topic 3 Combustion Instability and hydrodynamic Stability of Reacting Flows

(Coordinators, Tim Lieuwen and Jacqueline H. Chen)


Topic 4 Near-limit detonation and flame dynamics 

(Coordinator, Antonio L. Sanchez and Hoi Dick Ng)


The program of each topic/session will be coordinated by the topic coordinators. The information of invited speakers, position speakers, and highlight speakers will be updated on the workshop website as soon as the program is finalized. The scientific committee welcomes volunteers to give highlight talks.
