Abstract

"Sub-micron particulates emitted from various combustion sources have serious negative impacts on human health and the environment. It is essential to accurately characterize the physical properties of these particulates including size, shape, structure, and chemical composition in order to monitor, regulate, and model the various transport, toxic, optical, chemical, and deposition properties which dictate their harmful effects. This study consists of two related investigations involving the application of diagnostics methods to characterization and comparison of combustion generated particulate emissions from various sources. The first investigation includes the measurement of particulates emitted from a compression-ignition (diesel) engine using two independent measurement methods based on microscopy and mobility sizing and comparing the results. The two methods are markedly different in their approach to measuring the distributions of particle sizes, and each has its own advantages and disadvantages. However, there is no established relationship which correlates the size information provided by each method. So a careful comparison of the results is performed. In the second investigation, particulate emissions from compression-ignition engines, spark- ignition engines, and coal power plants are investigated for individual characterization and comparison using electron microscopy image analysis. Identifying key differences in the morphology and composition of the particulates emitted from these three combustion processes will extend the particulate knowledge base for the combustion community and may aid in the identification of significant sources in heavily polluted locations and allow for improved emission reduction strategies"--Abstract, page iii.
