Basic Picture A real detonation has a rich cellular structure quite unlike the simple 1D picture. 1D picture 2D & 3D picture Maximum pressure triple-point tracks On the Cellular Structure of Carbon Detonations (2000) In this article we present the results of a numerical study on two-dimensional carbon detonations. For an upstream density of 10$^7$ g cm$^{-3}$ the length-to-width ratio of the detonation cells is about 1.6 and is not strongly dependent on the spatial resolution of the simulation. However, the curvature of the weak incident shocks, strength of the triple points and transverse waves, and sizes of the underreacted and overreacted regions all depend strongly on the spatial resolution of the calculation. These resolution studies help define the minimum resolution required by multidimensional Type Ia supernovae models where the cellular structure of a detonation front is a key feature of the model. These 2D and 3D cellular detonation models won the Gordon Bell Prize in High Performance Computing, Special Category at Supercomputing 2000. Additional 2D and 3D visualizations from this effort are avaliable. 2D, maximum pressure 2D, temperature 2D, silicon 3D pressure mp4 movie 3D max pressure tracks mp4 movie 3D silicon mp4 movie
