Flame Acceleration in Channels with Obstacles in the Deflagration-to-Detonation Transition
Damir Valiev, Vitaly Bychkov, V'yacheslav Akkerman +2
It was demonstrated recently in Bychkov et al., Phys. Rev. Lett. 101 (2008) 164501, that the physical mechanism of flame acceleration in channels with obstacles is qualitatively di…
Analysis of flame acceleration induced by wall friction in open tubes
V'yacheslav Akkerman, Chung K Law, Vitaly Bychkov +1
Spontaneous flame acceleration leading to explosion triggering in open tubes/channels due to wall friction was analytically and computationally studied. It was first demonstrated t…
Coordinate-free description of corrugated flames with realistic density drop at the front
Vitaly Bychkov, Maxim Zaytsev, V'yacheslav Akkerman
The complete set of hydrodynamic equations for a corrugated flame front is reduced to a system of coordinate-free equations at the front using the fact that vorticity effects remai…
On the theory of turbulent flame velocity
Vitaly Bychkov, Vyacheslav Akkerman, Arkady Petchenko
The renormalization ideas of self-similar dynamics of a strongly turbulent flame front are applied to the case of a flame with realistically large thermal expansion of the burning…
Reduction of over-determined systems of differential equations
Maxim Zaytsev, Vyacheslav Akkerman
It is shown how the dimension of any arbitrary over-determined system of differential equations can be reduced, which makes the system suitable for numerical solution modeling. Spe…
Gas compression moderates flame acceleration in deflagration-to-detonation transition
Vitaly Bychkov, Damir Valiev, V'yacheslav Akkerman +1
The effect of gas compression at the developed stages of flame acceleration in smooth-wall and obstructed channels is studied. We demonstrate analytically that gas compression mode…
