燃燒反應(yīng)動(dòng)力學(xué)研究進(jìn)展
[Abstract]:Chemical reaction kinetics is an important tool for combustion process analysis. Great progress has been made in the research of combustion microscopic reaction process, complex reaction mechanism, combustion experimental measurement and turbulent combustion numerical simulation. In this paper, the research methods of combustion reaction kinetics are introduced, including the electronic structure method, the calculation method of combustion reaction thermodynamics and rate constant, the construction and simplification of combustion detailed mechanism, the molecular simulation of reaction force field and the measurement of combustion intermediates. Research status of fuel ignition delay and spectral diagnosis. Combustion reaction kinetics has a strong application background. The calculation of reaction rate of chemical species in combustion process is a central task in the numerical simulation of turbulent combustion. Because of the high complexity of combustion reaction network, our understanding of combustion mechanism is far from clear. The further study of the interaction between chemical reaction and turbulence and the coordinated development of combustion reaction kinetics and computational fluid dynamics will have a profound impact on the design of new fuel, the numerical simulation of combustion and the accurate description of the flow field structure in the inner flow channel of the engine.
