Rhelogical properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, June 15, 1992--September 15, 1992

摘要

The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to CWS. A correlation between the extensional and high shear properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS. During the past quarter, several experimental studies on pressure dependent atomization of Coal-water slurries and simulated fluids were performed. Also surface tension, elastic, high and low shear viscosities were performed. These tests were performed to initiate the understanding of the fundamental parameters that govern the atomization process of CWS.
