| Popis: | We have entered a new era in turbulent combustion calculations, where we can now simulate a detailed laboratory-scale turbulent reacting flow with sufficient fidelity that the computed data may be expected to agree with experimental measurements. Moreover, flame simulations can be used to help interpret measured diagnostics, validate evolving flame theories, and generally allow exploration of the system in ways not previously available to experimentalists. In this paper, we will discuss our adaptive projection algorithm for low speed reacting flow that has helped make these types of simulations feasible, and two sets of new issues that are associated with application of this approach to simulating real flames. Using a recently computed flame simulation as an example, we will discuss issues concerning characterization of the experimental conditions and validation of the computed results. We also discuss recent developments in the analysis and interpretation of extremely large and complex reacting flow datasets, and a new approach to simulating premixed turbulent flames relevant to laboratoryscale combustion experiments-a feedback-controlled flame stabilization method. |
