Recent Progress on Non-ideal Detonation

Abstract

Detonation are supersonic combustion waves composed of a reaction zone coupled to a leading shock wave. This seminar focuses on recent studies performed on different non-ideal aspects of detonation waves. In the first part, near-limit detonations are investigated using a long spiral tube facility. Improved design and methodology were employed to enable a better characterization of the detonation propagation in the stuttering and galloping regimes. In the second part, the impact of real gas effects on detonation initiation and structure was studied using a combination of theoretical and numerical approaches. In the third part, the impacts of chemical kinetics uncertainty and thermal non-equilibrium on the velocity and structure of pathological detonation in H2-Cl2 mixtures were investigated. 

Dr Rémy Mével is an Associate Professor at the Center for Combustion Energy and School of Vehicle and Mobility at Tsinghua University. He obtained his BSc (2004), MSc (2006), PhD (2009), and HDR (2015) from the University of Orléans, in France. He has been an Adjunct Professor at the University of Orléans in 2009-2010, and a Postdoctoral Scholar and a Research Scientist at the California Institute of Technology from 2010 to 2017. Dr Mével’s research focuses on chemical kinetics, laser diagnostics, and spectroscopy with application to industrial safety through the determination of fundamental combustion parameters and the study of detonation waves’ structure and dynamics. He has co-authored more than 80 journal articles and has been awarded the Gérard de Soete Prize in 2010 and the J.H.S. Lee Young Investigator Award in 2013 as a recognition of the quality of his work. In 2017, he was selected as a 1000 Young Talents of China.
