      abstract     = {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.},
