 Prof. Philippe Dagaut, CNRSINSIS, ICARE, France 报告题目：Probing combustion chemistry using devices ranging from reactors to internal combustion engines （报告下载）  
摘要：Recent advances in combustion chemistry are presented. They concern experimental and modeling studies of the oxidation of a range of synthetic and/or biofuels performed in jetstirred reactors, combustion chambers, and internal combustion engines. The experimental results were used to propose and validate detailed chemical kinetic reaction mechanisms and better understand the formation of pollutants and kinetically controlled ignition by active species. 


 Prof. Kang Y. Huh, Pohang University of Science and Technology 报告题目：Conditional Averaging Concept for TurbulenceChemistry Interaction in Turbulent Reacting Flows （报告下载）  
摘要：Conditional averaging has been a powerful tool to resolve turbulencechemistry coupling to estimate nonlinear chemical reaction rates in turbulent reacting flows. It is a rigorous mathematical procedure to derive the transport equations for conditional moments and associated pdfs which together lead to the Favre mean equations of engineering interest. This presentation is intended to introduce the basic concepts and important results from the conditional averaging approach in turbulent premixed and nonpremixed combustion. It has been a useful practice to represent the conditional flame structures in terms of the mixture fraction in turbulent nonpremixed flames. The CMC (conditional moment closure) model seeks a solution for the conditional mean transport equations with appropriate closure models for the conditional mean scalar dissipation rate and reaction rates. Recently there were new versions of the CMC model that require reduced computational load, e. g., the Lagrangian CMC with a finite number of flame groups with Lagrangian identities and the Eulerian CMC with tabulated chemistry to avoid direct integration of stiff elementary reaction steps. It will be shown that the stretched laminar flamelet model is in general not valid with crucial effects of the flamelet thickness varying with local curvature in turbulent premixed combustion. The leading edge is in the nonflamelet regime where turbulent and molecular diffusion combine with negligible reaction in analogy with the convectiondiffusion layer in a laminar premixed flame. The flame surface density and brush thickness adjust each other through a flame brush to match the turbulent burning velocity imposed at the leading edge in a steadily propagating flame. It will be shown that a parabolic profile of the flame surface density in the mean reaction progress variable space is closely associated with mean orientation vector and mean absolute curvature remaining approximately constant except at the edges. Further work is going on to develop new RANS and LES models in OpenFOAM for application of turbulent nonpremixed and premixed flames in various laboratory and industrial combustion devices. 


 Prof. Tim Lieuwen, Georgia Institute of Technology 报告题目：Fundamental Turbulent Combustion Questions for a Clean Energy Future （报告下载）  
摘要：Premixed combustion has emerged as one of the key strategies for enabling clean combustion systems. One of the fundamental observations in turbulent, premixed combustion is that the reactant consumption rate increases with turbulence intensity. A common explanation for this phenomenon, due to Damköhler, is that this is due to increases in flame surface area with turbulence intensity. A second approach, suggested by Zel’dovich and finding some theoretical foundations in the Kolmogorov–Petrovsky–Piskunov (KPP) theorem, is that the increase is due to an increase in velocity of the leading edge of the flame as it propagates into low velocity regions ahead of it. What is not often discussed in the combustion community is that these interpretations are fundamentally different  one argues that increases in flame area are the cause of increases in turbulent burning rate, and the other that it is an effect. This talk will discuss the factors influencing the turbulent burning rate in premixed flames, utilizing these two interpretations as a motivator for needed future research. 


 Prof. Kaoru Maruta, Tohoku University 报告题目：LowSpeed Counterflow Flame Experiments under Microgravity at Low Lewis Numberstoward Comprehensive Combustion Limit Theory （报告下载）  
摘要：Combustion limits and nearlimit flame behavior of flammable gaseous premixtures were investigated with microgravity experiments and computations. 1D computations with detailed chemistry, and 1D & 3D computations with diffusivethermal model were conducted to analyze experimental results. Special attention was paid to low Lewis number premixtures for constructing comprehensive combustion limit theory. Prior to the space experiment at Japanese module of the International Space Station scheduled from 2020, preliminary microgravity experiments with parabolic flight airplane have been conducted and successfully captured transitions from ordinary deflagration flame to flame balllike and sporadic flame phenomena in lowspeed counterflow flame configuration for CH4/O2/Xe mixture. Current prediction of overall picture of comprehensive combustion limit theory is presented.
