摘要

摘要随着烟尘颗粒的长大，它会发生一系列显著的形态变化（称为老化），从而导致颗粒表面的反应性降低。这项研究利用反应分子动力学来研究气相中乙炔分子与不同成熟度的烟尘颗粒表面之间的相互作用。结果表明，"年轻 "烟尘颗粒的分枝形态及其表面纳米级空隙的存在可能是对烟尘颗粒较高反应性产生重大影响的另一种效应。

Influence of the Surface Morphology of Soot Particles on Their Growth Kinetics: A Molecular Dynamics Study

Abstract

As a soot particle grows, it undergoes a number of significant morphological changes (called aging), which lead to a decrease in reactivity of the particle surface. This work uses reactive molecular dynamics to study the interaction between acetylene molecules in the gas phase and the surface of soot particles of varying degrees of maturity. It is demonstrated that the branched morphology of “young” soot particles and the presence of nanosized voids on their surface can be another effect that has a significant impact on the higher reactivity of soot particles.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
