Abstract
Self-ignition of hydrogen-air mixtures has been studied experimentally . This process was initiated behind a reflected shock wave at an initi al pressure of up to 0.5 MPa and with hydrogen volume contents ranging from 9.5-20 and 40-60%. Simultaneous recording of pressure and temper ature profiles near the end of a shock: tube made it possible to revea l the specific features of various self-ignition regimes and the regio ns of their existence. The peculiarities of the realization and evolut ion of mild and strong self-ignition processes are discussed, and a co mparison with self-ignition of carbon-air mixtures is done.
