Aerosol Physics: Optics, Gelation and Turbulent Aggregation

摘要CTS-0080017 C。M.索伦森，堪萨斯州立大学的PI建议，以扩大他在气溶胶聚集动力学的静态光散射诊断的发展所获得的结果。 这些测量将扩展到包括大颗粒（包括湍流范围内的一些颗粒），以及一些需要时间分辨率的情况。 一些需要的理论工作计划，分形聚集体散射的特点，并推广这些评估均匀的球形气溶胶。 快速显微摄影将提供对颗粒尺寸和形态的洞察。 这些定量的结果将使气溶胶和湍流聚集的动力学特性成为可能。一个特别的努力将是建立Smoluchovski方程的有效性限制，这似乎不适合一些早期测量的动力学在稀释或湍流系统。 簇分形数据将产生超出扩散（层流）制度的演变，而密度场将确定偏离平均场行为。

AbstractCTS-0080017C. M. Sorensen, Kansas State UniversityThe PI proposes to extend the results he has obtained in the development of static light scattering diagnostics of aerosol aggregation kinetics. These measurements will be extended to include large particles (including some in the turbulent range), and also some cases in need of time resolution. Some needed theoretical work is planned, to characterize the fractal aggregate scattering, and also to generalize these assessments to homogeneous spherical aerosols. Fast microphotography will give an insight of the particles size and morphology. These quantitative results will make possible the kinetics characterization of aerogelation and turbulent aggregation.A special effort will be to establish the validity limits of the Smoluchovski equation, which does not seem to fit some of the earlier measured kinetics in dilute or turbulent systems. Cluster fractal data will yield the evolution beyond the diffusional (laminar) regime, while density fields will identify deviations from mean-field behavior.
