The Fundamentals Of Aerosol Dynamics

During the past 30 years, there have been advances in the understanding of multi-particle hydrodynamic interactions in the field of aerosol dynamics. Aerosol dynamics is developing from isolated-particle stage into multi-particle stage. This book reviews these progresses, and the subjects it covers include sedimentation, coagulation, mass or heat transfer, effective viscosity, and the evolution of the size distribution.

Publisher Description

The Dynamics of Aerocolloidal Systems, Volume 1 is concerned with the dynamical behavior of idealized aerosol particles in the light of developments in classical mechanics. The idealization is based on the assumption that the solid or liquid particles suspended in a gas can be modeled as macroscopically smooth, chemically inert, spherical bodies. Topics covered include transport processes, single particles, and generation and behavior of clouds. Emphasis is placed on fluid dynamics from the continuum regime to the free molecule regime. This book is comprised of 10 chapters and begins with an overview of definitions and classifications of aerocolloidal suspensions. The next chapter deals with the characteristics of aerial dispersions as provided for in the hard, smooth sphere picture. The basic mechanical parameters of an aerocolloidal system is described, along with certain different regimes of the idealized aerosol and various solutions of the Boltzmann equation. The reader is methodically introduced to the dynamics of single particles in the continuum approximation; heat and mass transfer to single particles in a continuum; formation of aerosols by nucleation of supersaturated vapor; and diffusion and dispersion of aerosol particles. The final chapter considers the interaction between aerosol particles, paying particular attention to the collision of inert spheres whose sticking probability is unity. This volume will be useful to scholars, practicing scientists, and graduate students as well as those who would consider teaching aerosol mechanics as part of a curriculum in the atmospheric sciences, or in other applied sciences including applied physical chemistry, and engineering.

Topics in Current Aerosol Research deals with the fundamental aspects of aerosol science, with emphasis on experiment and theory describing highly dispersed aerosols (HDAs) as well as the dynamics of charged suspensions. Topics covered range from the basic properties of HDAs to their formation and methods of generation; sources of electric charges; interactions between fluid and aerosol particles; and one-dimensional motion of charged cloud of particles. This volume is comprised of 13 chapters and begins with an introduction to the basic properties of HDAs, followed by a discussion on the formation of condensation HDAs. Some of the methods of generation of HDAs are considered, including atomization, physical condensation of vapor, and chemical reactions in the gas phase are considered. A ""transport"" model for electrically charged aerosols is described. Subsequent chapters explore methods of investigation of HDAs in suspended state and based on particle precipitation; transfer processes in HDAs, including mass transfer, charge transfer, momentum transfer, and heat transfer; and charging of particulate matter by collection. This book will be a useful resource for practicing scientists and graduate students in such widely diverse fields as physics, physical chemistry, meteorology, geophysics, astronomy, chemical engineering, mechanical engineering, aerospace engineering, environmental sciences, and medicine.
