Investigation of the effect of coal particle sizes on the interfacial and rheological properties of coal-water slurry fuels. Quarterly report No. 2, October 1, 1995--December 31, 1995

Description

Experiments have been performed to simulate the effects of high viscosity and surface tension of CWS fuel on its atomization. Aqueous solutions of glycerol simulated the high viscosity condition of CWS fuels and ethanol solutions allowed to separately investigate the effect of surface tension. A Fraunhofer diffraction particle sizing technique measured the spatial distribution of Sauter mean diameters (SMDs) for the cross injecting sprays which were previously described in the Quarterly Report No. 1. Experimentally determined parametric correlations reveals the dependence of the spray SMDs on the liquid viscosity, surface tension, the air flow rate, the liquid flow rate, the ... continued below

Description

Experiments have been performed to simulate the effects of high viscosity and surface tension of CWS fuel on its atomization. Aqueous solutions of glycerol simulated the high viscosity condition of CWS fuels and ethanol solutions allowed to separately investigate the effect of surface tension. A Fraunhofer diffraction particle sizing technique measured the spatial distribution of Sauter mean diameters (SMDs) for the cross injecting sprays which were previously described in the Quarterly Report No. 1. Experimentally determined parametric correlations reveals the dependence of the spray SMDs on the liquid viscosity, surface tension, the air flow rate, the liquid flow rate, the orifice nozzle diameter, and the measurement locations. This simulated correlation will provide important guidelines for the actual CWS spray experiment to be performed in the successive quarter.
