Formation and Size Distribution of Submicron Aerosol Agglomerates

提出了对高温工业过程中气溶胶形成的系统研究。该项目将理论分析与相关实验相结合，以理解成核、量化团聚体结构、确定颗粒形成和生长的尺度规律、模拟团聚体的自保尺寸分布等几个一般研究目标为指导。该方法基于选择性实验和颗粒生长的基本特征的建模，作为初始尺寸分布的函数，二元气溶胶的团聚，火焰中陶瓷粉末的形成和颗粒收集。预计该项目如果成功，将在高温下的气溶胶科学中取得有价值的成果，特别是在通过凝聚-聚结过程形成初级粒子方面，并应用于火焰中先进材料的合成。

A systematic study of aerosol formation in high temperature industrial processes is proposed. The P.I. combines theoretical analysis with relevant experiments, guided by several generic research goals related to understanding nucleation, quantifying the structure of agglomerates, identifying scaling laws for particle formation and growth, and modeling self preserving size distribution of the agglomerates. The approach is based on selective experiments and modeling of the essential features of particle growth as a function of the initial size distribution, agglomeration of binary aerosols, formation of ceramic powders in flames, and particle collection. It is expected that this project, if successful, will lead to valuable results in aerosol science at high temperature, particularly on primary particle formation by coagulation- coalescence processes, with application to advanced materials synthesis in flames.
