Two-Dimensional Euler Adaptive Mesh Method on Detonation

    Abstract
  • The adaptive mesh refinement (AMR) method is applied in the 2-D Euler multi-component elastic-plastic hydrodynamics code (MEPH2Y). It is applied on detonation. Firstly, the AMR method is described, including a conservative spatial interpolation, the time integration methodology with the adapitve time increment and an adaptive computational region method. The advantage of AMR technique is exhibited by numerical examples, including the 1-D C-J detonation and the 2-D implosion ignited from a single point. Results show that AMR can promote the computational efficiency, keeping the accuracy in interesting regions.
