报告摘要
Recent concerns over energy sustainability have presented great challenges to develop quantitatively predictive models to enable new technologies and renewable fuels for energy systems to increase energy conversion efficiency and reduce emissions. This talk will present a summary of the recent progresses in experimental and kinetic studies of transportation fuels as well as low temperature plasma assisted combustion. The talk will discuss the challenges of experiments and kinetic modeling of ignition, extinction, and emissions at high pressures using various alternative fuels with different functional groups. A generic concept of surrogate fuel model using a few selected component fuels to model the burning and emission properties of real fuels will be presented and validated. A comprehensive correlation between flame extinction and fuel functional groups will be discussed. A multi-time scale model to achieve efficient modeling of combustion with a detailed mechanism will be presented. The theory of flame initiation will be revisited and the important length scales which govern the minimum ignition energy and flame extinction will be analyzed. Based on the theoretical and kinetic understanding, a non-equilibrium plasma assisted combustion technology to achieve low temperature ignition and enhance flame stabilization will be presented.
