| Adaptive Mesh Refinement Strategy for Detonation Wave Simulations |
| Historically, detonation waves have been characterized using the Chapman-Jouguet (CJ) and Zel'dovich-von Neumann-Doring (ZND) models. Although these 1D models are useful for many applications, they are unable to capture the 3D nature of the wave. Three-dimensional modeling has been reported in the literature in recent years, but an accurate model must resolve wide ranges of length and time scales from the fluid and chemical kinetics that causes numerical stiffness. For this research topic, adaptive mesh refinement techniques are utilized to resolve all spatial and temporal scales while reducing the number of grid cells. Detailed results of work completed on this topic can be found among the recent conference papers. |
