Talk Title: Advances in Computer Simulations of Turbulent Combustion

Abstract: Combustion will remain a key technology for several decades in power generation, transportation and many other applications. Advances are continually sought in terms of efficiency gains, pollution reduction, and alternative technologies facilitating carbon capture. As in other areas of engineering, computer simulations are central to the design and development of combustion technologies. Great strides are being made both in the computation fluid dynamics (CFD) of turbulent reactive flows and in the development of more accurate and comprehensive chemical mechanisms, which may involve thousands of species. However, the combination of advanced approaches to turbulent flows and large chemical mechanisms poses a formidable computational challenge. The approach to the simulation of turbulent combustion described in this talk consists of the following three components: large-eddy simulation (LES) to treat the flow and turbulence; a probability density function (PDF) method to treat the turbulence-chemistry interactions; and, dimension-reduction and tabulation for the computationally-efficient implementation of combustion chemistry. Recent advances and examples of simulations are presented.
