Atomization of Coal Water Slurry Sprays 940327

The atomization of coal water slurry (CWS) sprays is modeled using the aerodynamic theory of atomization. Several extensions to the theory have been explored to account for the non-Newtonian behavior of the slurry. For comparison with experiment the following spray parameters are identified; spray angle, intact core length, drop diameters, and velocities of drops and gas. Results from computer simulations that use the CWS atomization model have been compared with recent experimental data, particularly with the transient development of the spray. Good agreement between experiments and computations has been found.
