Advancements in the CFD Modeling of Clean Coal Technologies

摘要

Future improvements to the efficient utilization of coal as an energy resource and reductions to plant emissions require continuing advancement in technology for coal combustion and flue gas treatment. Computational fluid dynamics (CFD), which has long been a valuable tool for engineering design and optimization, is rapidly increasing in capability and performance to assist and enable the development of next-generation clean coal technologies. The challenge of modeling coal systems is immense: complex particle-fluid physics, a multitude of chemical reactions, mass-transport processes, and heat transfer are being computed at a massive scale to simulate industrial systems with complex, "real-life" geometric features. To meet these challenges, important advances in modeling have been made which range from the computation of more detailed physics and chemistry to substantial performance increases created by the use of new computer hardware. These advances have been largely driven by the needs of industrial and academic CFD users, a group for which clean coal applications have great importance.
