Design of atomizers and burners for coal-water slurry combustion

PDF Version Also Available for Download.

Description

In order to measure the extensional viscosity of polymeric solutions and coal water slurries (CS) a novel free-fall extensional device will be developed and its usefulness in measuring the extensional viscosity will be demonstrated. Photographic visualization of the breakup of viscoelastic materials in the drip mode has shown that these materials exhibit completely different breakup patterns when contrasted to viscoinelastic materials. The ligaments were seen to undergo a very large stretching motion before they breakup, resulting in long threads of liquid attached to droplets. The drip mode of breakup can be used to extract useful information on the extensional properties ... continued below
