Abstract
This work aims to show that an LES combustion model with Eulerian stochastic fields and tabulated chemistry can successfully describe the flame dynamics of a premixed turbulent flame. The chemistry is tabulated in progress variable and enthalpy, using one-dimensional burner stabilized flamelet computations. The progress variable allows for tabulation of a reaction scheme of any complexity and the enthalpy tabulation ensures a reduced reaction rate due to heat losses. The turbulence-chemistry interaction is modeled by 8 Eulerian stochastic fields. LES of a premixed swirl burner for three different operating points are performed to investigate the flame dynamics. A velocity broadband excitation is used to identify a flame transfer function. The preliminary study on a coarse mesh shows that the identified flame transfer function is in qualitative agreement with experimental data but simulations on fine grid are required to get accurate results.We do not need a test account, since we have already done the required testing. Thus, we apply directly for a full account (please see the proposal provided in a separate document).
