| 520 | _ | _ | |a Studying the interplay between a hydrogen flame and turbulence is crucial for the advancement of next-generation carbon-neutral combustion systems. In our present work, we conduct a series of direct numerical simulations (DNS) to investigate the dynamics of a premixed hydrogen flame interacting with the compressible homogeneous isotropic turbulence (HIT) maintained by a deterministic force under different pressure and turbulence intensity. Under this particular forcing method applied to turbulence at large scales, the relationship between the forcing intensity and the resulting fluctuating velocity aligns well with the experimental results. In our study, we compared the normalized turbulent burning velocity of hydrogen flames under different conditions, verified the common occurrence of bending effects at elevated pressures and validated existed turbulent burning velocity models. To further explore the dynamics of the HIT-flame interaction and fully leverage the advantages of high-precision direct numerical simulations, we analyzed several flame behaviors such as stretch and instability. The probability density functions (PDF) for the tangential strain rate and curvature are displayed and the results indicate a strong correlation between the flame surface structure and the turbulence generated by the large-scale forcing. |
