- Abstract
- The Direct-Quadrature Method of Moments (DQMOM) based transported probability density function model has been applied to simulate turbulent H₂ lifted flame. To realistically account for precise turbulent flame structure of turbulent lifted flame, Eulerian transported PDF method is based on the joint-composition PDF model with IEM mixing process. To predict detailed auto-ignition process and conditional fluctuations on composition space, all composition vector including species mass fraction and enthalpy is directly integrated with DVODE solver. The unconditional means and conditional scatters in terms of species mass fraction and temperature calculated from the present model are compared with experimental data. Numerical results indicate that the present DQMOM approach has the capability to predict autoignition, local extinction, and reignition in the vitiated jet flame. In terms of the lifted-off height, mean and rms of species massfraction, the predicted profiles are reaonably well agreed with experimental data.
