Three-dimensional reactive flow models

Two-dimensional models realistically reproduce the in-channel fluid mechanical transport and, when coupled with detailed hetero-Z homogeneous chemistry, provide a powerful tool for both reactor design and fundamental research. Three-dimensional (3D) reactive flow models are necessary in complex geometries with nonstraight channels and cross-flow between channels used for achieving reactor radial uniformity. ZUthough 3D effects do play a role even for straight-channel honeycomb...

The effect of two volume percent spherical air holes on the reaction zone was modeled using the three-dimensional Eulerian hydrodynamic code, 3DE. The air holes perturb the reaction zone flow. A complicated reaction region develops and is maintained by the reactive fluid dynamics.
