Direct Numerical Simulations of the Impact of High Turbulence Intensities and Volume Viscosity on Premixed Methane Flames

Figure 2

General view of the configuration for the direct simulation, showing (a) the iso-surface of temperature with H₂O₂ slices and (b) CO₂ slices with stream lines (thin white lines), revealing the heavily wrinkled flame front after interacting with the three-dimensional time-decaying homogeneous isotropic synthetic turbulent velocity field for 0.8 millisecond.
