Description The multidimensional structure of mildly unstable detonations are examined by numerical computations. Thesephenomenon have grown in interest since the development of propulsion devices such as pulsed and rotating detonationengines. Rectangular, diagonal and spinning modes are observed in a near-limit propagation detonation. High-ordernumerical integration of the reactive Euler equations have been performed to analyze the averaged structure, the shockdynamics of a single-cell detonation propagating in a square channel. Computations show a good agreement with theexperimental cellular structure, showing the relevance of the slapping waves in the rectangular modes. The hydrodynamicthickness as well as the pdf shock dynamics are similar in the 2D and 3D cases, but the mean quantities vary on aquantitative basis. Moreover, the presence of strong forward jets is attested, which comes from simultaneous triple pointline collisions with the walls.
