Spectral Energy Transfer in Turbulent Flames: from its Characterization to Subgrid Scale Models
Abstract
This proposal focuses on the effects of the flame on the turbulent flow field, and more precisely on theenergy transfer process between scales. This is one of the two pillars of turbulent combustion. The other pillar relates to the effects of turbulence on flame chemistry and has been investigated much more heavily. Furthor, this proposal seeks to challenge this assumption and quantify for the first time the effects of chemistry and the attendant heat release on the small-scale dynamics of the turbulent flow. More specifically, the objectives are to investigate the spectral energy transfer between scales, the expected increase in backscatter (energy transferred from small to large scales), and use thisinformation to develop mathematically-consistent, non-empirical SGS models designed specifically for turbulent reacting flows.
