ABSTRACT CTS-9408153 C. Sorenson Static and dynamic light scattering techniques will be developed to study properties of the fractal aerosol clusters, including morphology, diffusional transport, optical scattering properties and aggregation kinetics. Aggregates of particles formed through coagulation processes are described as fractals, which allows for improved measuring techniques and overall physical understanding. The experiments will be performed with carbonaceous soot aerosols in premixed flames, and silica and titania aerosols. The proposed measuring techniques have scientific relevance, and may be applied to studies related to aerosols and colloids in industrial processes, environmental aerosol analysis, combustion, and nuclear reactor safety. ***

摘要CTS-9408153 C.索伦森 静态和动态光散射技术将被开发来研究分形气溶胶团簇的性质，包括形态，扩散传输，光散射特性和聚集动力学。 通过凝聚过程形成的颗粒聚集体被描述为分形，这使得测量技术和整体物理理解得到改进。 实验将进行预混火焰中的碳烟气溶胶，二氧化硅和二氧化钛气溶胶。 所提出的测量技术具有科学相关性，并可应用于与工业过程中的气溶胶和胶体、环境气溶胶分析、燃烧和核反应堆安全相关的研究。 ***
