Implementation of a Robust Weighted Compact Nonlinear Scheme for Modeling of Hydrogen/Air Detonation

In order to simulate detonation, a high-order shock-capturing scheme that models chemical reactions is implemented, and its resolution is examined by testing it on several numerical problems. A robust weighted compact nonlinear scheme (RWCNS) is adopted to take advantage of its robustness and abilit...

Description
Summary:	In order to simulate detonation, a high-order shock-capturing scheme that models chemical reactions is implemented, and its resolution is examined by testing it on several numerical problems. A robust weighted compact nonlinear scheme (RWCNS) is adopted to take advantage of its robustness and ability to handle different flux types. This study shows the high resolution of the RWCNS compared with the conventional scheme. The results show that the RWCNS predicts the detailed vortex structure behind the detonation wavefront.
