Abstract:
Results of an experimental study of continuous spin and pulsed detonation of hydrogen-oxygen and acetylene-oxygen mixtures in a flow-type annular combustor $10$ cm in diameter with channel expansion in the regime of oxidizer ejection are presented. Through comparisons with the mechanical analogy of a piston-driven pump, it is found that the detonation wave serves as a pump for the oxidizer, and the rarefaction wave serves as a suction piston. Stable regimes of continuous spin detonation with one transverse wave are observed under the test conditions used; the wave velocity is $D=1.76-1.6$ km/sec for hydrogen and $D=1.46-1.2$ km/sec for acetylene. The frequency of the pulsed detonation wave is $7.3$–$5$ kHz in the $\mathrm{H}_2$–$\mathrm{O}_2$ mixture and approximately $2.5$ kHz in the $\mathrm{C}_2\mathrm{H}_2$–$\mathrm{O}_2$ mixture.
