Design of atomizers and burners for coal-water slurry combustion. Progress report, April 1--June 31, 1996
In the period extending from March 30th to June 30th 1996 the following tasks were completed. The authors have successfully developed the falling droplet technique to measure the extensional viscosity of very dilute polymeric solutions. They have also determined that the polymeric materials used behaved as elastic solids even at very low concentrations of the order of 30 ppm. A published paper contains a complete description of the technique and is enclosed within this report. They have designed and built the air-assist effervescent atomizer. They have mounted the atomizer to the spray chamber. They have set up the phase Doppler to make droplet size and velocity measurements in the flow field of the air assist effervescent atomizer.
