Аннотация:Levin V.A., Manuylovich I.S., Markov V.V. Multiheaded Rotating Detonation in an Annular Gap. Dokl. Phys. 67, 23–26 (2022). https://doi.org/10.1134/S1028335822010050https://link.springer.com/article/10.1134/S1028335822010050AbstractThe flows in a combustion chamber shaped as an annular gap between plates with multiheaded rotating detonation of the propane–air mixture entering the chamber in the direction of the symmetry axis from the reservoir with the stagnation parameters specified are investigated numerically. The conditions for the formation of a preset number of waves in the multiheaded detonation wave are determined; they are associated with the dimensions of the combustion chamber and the parameters of the initiators. The values of the highest number of waves for the specified dimensions of the combustion chamber are obtained. It is found that the existence of the highest critical value of the number of waves in the multiheaded detonation is associated with blocking the feed of the combustible mixture. It is found that the mutual angles between the waves that make up the multiheaded detonation are gradually aligned with an uneven arrangement of initiators. For the calculations carried out on the Lomonosov supercomputer of Moscow State University, an original computer complex based on the modified Godunov method and one-stage reaction kinetics is used.
