Abstract:
The results of an experimental study of initiation of hydrogen combustion in a supersonic flow with fuel supply from the channel wall are presented. Data are obtained on the dynamics of disturbance development from gas-dynamic pulses and on the transition to the combustion mode in a pseudo-shock, when fuel is supplied from the combustion chamber walls rather than along the flow axis. Features of pre-detonation combustion initiation for such a scheme of hydrogen supply to a supersonic flow are revealed. It is shown that the steady-state modes of pre-detonation combustion slightly differ depending on the fuel supply method (along the axis or from the flow periphery), while the dynamics of wave structure propagation from gas-dynamic pulses is almost identical in both cases.
Keywords:supersonic flow, wave structures, combustion in pseudo-shock, pressure distribution.
