Combustion of pulverized coal in vortex structures. Quarterly progress report No. 2, January 1, 1994--March 31, 1994
This second quarterly report describes the activities and accomplishments of the research team at the University of Oklahoma, Norman, Oklahoma, related to the project entitled ``Combustion of Pulverized Coal in Vortex Structures`` during the period January 1, 1994 to March 31, 1994. The construction of the experimental facility for generating two-dimensional shear layers containing vortex structures has been completed. Preliminary shake-down test of the test facility were conducted for debugging and fine-tuning. A smoke generator was constructed for smoke-visualization of shear layers. Direct photographs of smoke flow patterns of the interfacial region of the mixing layers have been taken. Mean velocity profiles in the direction normal to the tunnel stream direction have been measured with a hot-wire anemometer for different ratios of the initial velocities of the mixing streams. In the next quarter, we plan to conduct schlieren flow visualization of the shear layer, fabricate the particulate feeding system, and measure the velocity field as a function of the particulate concentration in one of the streams.
