AB Unsteady three-dimensional detonations in both a circular tube and a coaxial tube are simulated in order to reveal characteristics of single spinning and two-headed detonations. The numerical results show a feature of a single spinning detonation which was discovered in 1926. Transverse detonations are observed in both tubes. However, the single spinning mode maintains the complicated Mach reflection, whereas the two-headed mode develops periodically from the single Mach reflection to the complex one. The instantaneous detonation velocities for the spinning mode change from 0.9&minus;1.1 <i>D<sub>CJ</sub> along the symmetry of axis, and those for the two-headed mode change from 0.8minus;1.4 <i>D<sub>CJ</sub> along the inner tube wall. Those along the outer tube for both modes vary from 0.75 <i>D<sub>CJ</sub> to 1.6 <i>D<sub>CJ</sub>
