Abstract:
The flow structure for various detonation regimes is numerically studied in a new
flow-type supersonic annular detonation combustor. In the combustor with a new design,
detonation burning of the reacting mixture is organized by using a compression body, shaped
as a continuous monofilar helix with a constant pitch angle. Numerical simulations are
performed for a supersonic flow of a stoichiometric hydrogen-air mixture with Mach number
M0=3 at the combustor entrance. A mathematical model of the reacting flow in the combustor
is developed in a two-dimensional unsteady formulation. The flow dynamics at the beginning
of combustor operation and the structure of the steady flow in the combustor are numerically
studied. Simulations are performed for various helix angles and combustor sizes. A bifurcation
of the steady flow structures with respect to the initial conditions of combustor operations is
detected for some combinations of the geometric parameters of the combustor.
