DETONATION INITIATION IN A CHANNEL WITH A MULTISTAGE FOCUSING ELEMENT
RÉSUMÉ
The experimental study of the conditions for the gas mixture deflagration-to-detonation transition in an installation equipped with a multistage focusing element in the form of a П-shaped insert has been carried out. To demonstrate the effectiveness of the proposed design, the various mixtures of propane and air were used. It is shown that a stable transition is observed in the propane concentration range of 3.8%-4.9%.
