|Abstract||A new structure of solution elements and conservation elements based on rectangular mesh was pro-
posed and an improved space-time conservation element and solution element (CE/SE) scheme with sec-
ond-order accuracy was constructed. Furthermore, the application of improved CE/SE scheme was
extended to detonation simulation. Three models were used for chemical reaction in gaseous detonation.
And a two-fluid model was used for two-phase (gas–droplet) detonation. Shock reflections were simu-
lated by the improved CE/SE scheme and the numerical results were compared with those obtained by
other different numerical schemes. Gaseous and gas–droplet planar detonations were simulated and
the numerical results were carefully compared with the experimental data and theoretical results based
on C–J theory. Mach reflection of a cellular detonation was also simulated, and the numerical cellular pat-
terns were compared with experimental ones. Comparisons show that the improved CE/SE scheme is
clear in physical concept, easy to be implemented and high accurate for above-mentioned problems.|
