Numerical simulation for laminar burning velocity of premixed hydrogen-air mixture

In order to investigate the adaptability of the combustion models to the laminar burning velocity of premixed hydrogen-air mixture, the numerical simulation of hydrogen laminar burning velocity has been conducted in this paper. First, it is verified and validated that at the equivalence ratio of 0.5 to 1.2, the mesh size is recommended to be 0.4 mm, the time step 0.01 ms and convergence criterion 10^-4. Then, a good consistency between the calculation result and experiment data has been reached by adjusting the main parameters of the turbulent flame speed closure(TFSC) model at different temperature and different equivalence ratio. Finally, based on the simulation configuration, the laminar burning velocity of premixed hydrogen-air mixture can be correctly calculated equivalence ratio from 0.5 to 1.2, and in a normal pressure environment with the temperature between 300 K to 900 K, which can be used as reference data in a high temperature environment.
