A numerical investigation of detonation propagation in
stratified reactant layers is presented in this paper. It is
baesed on the reactive Euler equations using a two step
chemical kinetics approach. The numerical simulations
are based on the reactive Euler equations. Turbulence is
solved with a one equation model, and the chemical kinetics
is modeled as a two steps. The first step is an induction
time step, and the second step is an exothermic step.
The numerical setup is scaled to keep the numerical resolution
of the induction zone constant to 10 cells. Initial
simulations were conducted to generate detonation structures
in homogeneous reactants and with cyclic boundary
conditions. The developed structures were mapped into
a domain with a stratified reactant layer on top of a inert
layer. The results show that the detonations fail to propagate
as the triple points of the propagating detonation is
"lost" into the inert layer.
