Deflagration and detonation are the modes of
combustion at subsonic and supersonic speed respectively.
Detonation is marked by sudden rise in pressure in the flow. In
this study, Deflagration to Detonation transition (ddt) is
numerically investigated in a homogeneous Hydrogen-air
stoichiometric mixture inside a tube of 1m length and 50 mm
diameter with obstacles. The two-dimensional compressible
Reynolds Averaged Navier Stokes equation is solved using open
source deflagration to detonation solver ‘ddtFoam’ at
OpenFoam platform. The obstacles here are the obstructions in
the flow for turbulence enhancement...(Refer to link below for full paper)

Title: Numerical Study of Deflagration to Detonation Transition in 2-D and Axisymmetric
Detonation Tube with Obstacles Using OpenFOAM
In this study, homogeneous Hydrogen-air mixture is numerically investigated in a tube of 1m length and 50mm
diameter with obstacles by solving two-dimensional compressible Reynolds Averaged Navier Stokes equation with reaction
modelling of hydrogen-air combustion, using open source deflagration to detonation solver ‘ddtFoam’ at OpenFoam platform.
Deflagration to detonation transition is observed in the tube at various time and locations...(Refer to link below for full paper)
