| Research Abstract |
Deflagration-to-Detonation Transition is numerically studied by using an AMR mesh method. We simulate flame acceleration and its transition to detonation in an open space with obstacles. The result shows that the flame speed and acceleration depend on the direction of flame propagation. The flame speed delays in the directions where the flow loses more momentum. In these directions, however, the flame quickly accelerates due to more shock-flame interactions, which also trigger DDT.
