柴油机碳烟颗粒物的分形生长分析与凝聚控制
The analysis and its agglomeration control of soot particles fractal growth
摘要
Abstract
Based on the fractal growth physical model of soot particles from large diesel agriculture machinery, this paper simulates the morphological structure of collision for the single particles and single particles, single particle and clusters, clusters and clusters, firstly. Moreover, combining with the collision frequency, the fractal growth is controlled to agglomeration using the main environmental factors interference for diesel engine soot particles, in order to make them condensed into regular geometry or larger density particles, reduce the viscous drag for capturing by the capturer or set-tlement and to realize the control of the pollution of the environment. The results of numerical simulation show that the proposed method are feasible and effective, which will help to understand and analyze the physical mechanism and kinetics of non-equilibrium condensation growth behavior of the actual carbon smoke particles and provide the solution to further reduce emissions of the inhalable particulate matter from diesel engines.关键词
