【 摘 要 】

The work detailed in this report addresses Enabling Technologies within Computational Technology by integrating a breakthrough particle-fluid computational technology into traditional Process Science and Engineering Technology. The work completed under this DOE project addresses five major development areas (1) gas chemistry in dense fluidized beds; (2) thermal cracking of liquid film on solids producing gas products; (3) liquid injection in a fluidized bed with particle-to-particle liquid film transport; (4) solid-gas chemistry, and (5) first level validation of models. Because of the nature of the research using tightly coupled solids and fluid phases with a Lagrangian description of the solids and continuum description of fluid, the work provides ground-breaking advances in reactor prediction capability. This capability has been tested against experimental data where available. The commercial product arising out of this work is called Barracuda and is suitable for a wide (dense-to-dilute) range of industrial scale gas-solid flows with and without reactions. Commercial applications include dense gas-solid beds, gasifiers, riser reactors and cyclones.
