Numerical Simulations of Gaseous Detonations

Detonations with Detailed Hydrogen-Oxygen Chemistry

Two-dimensional Simulations

Mach Reflection of a Detonation Wave, H2:O2:Ar / 2:1:7, T0 =298 K, p0 =10.0 kPa   Inflow Angle 60 Degree

Schlieren plots of the density and temperature field after 48 microseconds. The Mach reflection is clearly visible.

The Mach reflection leads to a high overdrive factor behind the Mach stem that suppresses the regular transverse oscillation and the detonation cells fade away.
