ABSTRACT
During the last 2 decades, there have been enormous strides in the application of computational fluid dynamics (CFD) to combustion. Driven by the widespread availability of inexpensive computing power, CFD is today being used to analyze applications as diverse as boilers and furnaces, fluidized beds, gas-turbine combustors, gasifiers, and many others. Increasingly, there is interest in simulating evermore complex geometries and to aggregate many complex subsystems to create very large-scale, system-level simulations. Unstructured CFD methods have played a central role in facilitating this expansion. Unstructured meshes reduce mesh generation time from months to weeks or even days. Coupled with advances such as solution-adaptive meshing, unstructured mesh CFD methods promise to greatly reduce human time in the simulation process, and integrate simulation and analysis in the design cycle.
