ABSTRACT

The effect of turbulization of a hydrogen-oxygen-air mixture flow on the deflagration-to-detonation transition in a pulse combustor (PC) is studied. The parameters of operation of the PC with flame front propagation in a quiescent and strongly turbulized mixtures (Re ≫ 104) are compared. It is shown that, in case of a quiescent mixture no detonation occurs because of a small length of the PC. The presence of intense pulsations (Re > 2 · 104) created by elements of special configuration in the mixing chamber promotes the formation of a detonation wave, the velocity of which depends on the fuel-to-oxidizer equivalence ratio.
