Adaptive Computation of Reactive Flows with Local Mesh Refinement and Model Adaptation

An adaptive method for reactive flows involving locally refined meshes and different types of diffusion models is proposed. Starting with a less exact diffusion model, the model is changed locally throughout the computational domain to a more accurate and much more expensive model. An a posteriori error estimator provides reliable information on where to refine the mesh and where to adapt the model. Discretization and modeling errors are equilibrated.
