Аннотация:We have made an experimental study of the ignition of a stoichiometric hydrogen–air mixture behind the incident shock wave front in a shock tube. The ignition limits and the induction times of the mixture behind the wave front in the range of temperatures T =550–960 K and pressures P =0.01–1.1 MPa have been determined. Much lower values of the ignition temperature compared to the experimental results obtained in reflected shock waves, as well as to the classical Lewis and Elbe, have been registered. The measured induction times in the above temperature and pressure ranges are in good agreement with theoretical estimates.
