  • Cylindrical cellular detonation was numerically investigated by solving the two-dimensional reactive Euler equations with finite volume method on a two-dimensional self-adaptive unstructured mesh. The one-step reversible chemical reaction model was used to simplify the control parameters of chemical reaction. Numerical results demonstrate the evolution of cellular cell splitting of cylindrical cellular detonation which has been explored by experimental results. The splitting of cellular structures shows different features in the near and far field from the initiation zone. The variation of the local curvature is a key factor for behaviors of cell splitting of cylindrical cellular detonation in propagation. Numerical results also show that the splitting of cellular structures is dominated by from the selforganization of transverse waves which correspond to the development of small disturbances along the detonation front related to detonation instability.
