Numerical Simulations of Gaseous Detonations

Detonations with Detailed Hydrogen-Oxygen Chemistry

Two-dimensional Simulations

This section presents simulations for H2:O2:Ar Chapman-Jouguet detonations with molar ratios 2:1:7 at T0 =298 K and p0 =6.67 kPa or p0=10.0 kPa. All simulations were done with AMROC.
