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). Several CWS were prepared and their low shear rheological properties (i.e. rheology as a function of concentration, constant shear and, additive type, stability and slip effect) performed. The stability was determined using a settling column to study the shift in mass of the CWS as a function of time. Low shear testing of the slurries were used to determine the effect of yield stress on the concentration of the slurries.
