Propagation Mechanism of Cylindrical Cellular Detonation

Abstract

We investigate the evolution of cylindrical cellular detonation with different instabilities. The numerical results show that with decreasing initial temperature, detonation becomes more unstable and the cells of the cylindrical detonation tend to be irregular. For stable detonation, a divergence of cylindrical detonation cells is formed eventually due to detonation instability resulting from a curved detonation front. For mildly unstable detonation, local overdriven detonation occurs. The detonation cell diverges and its size decreases. For highly unstable detonation, locally driven detonation is more obvious and the front is highly wrinkled. As a result, the diverging cylindrical detonation cell becomes highly irregular.

Macroscopic resonant tunneling in an rf-SQUID flux qubit under a single-cycle sinusoidal driving *

“…We also take intrawell and inter-well relaxation into consideration. If the ground state |0 in the initial well is aligned with the |n excited state of the final well, the relaxation rate of the |n excited state is Γ = nΓ 1 , [29] where Γ 1 is the relaxation rate of the first excited state. The resonant tunneling rate is given by…”

Numerical Investigation on the Propagation Mechanism of Steady Cellular Detonations in Curved Channels

“…This transverse initiation process is essentially the same as a cylindrical detonation. [12,13] However such a transverse detonation can only be observed in Figs. 3(a Two kinds of propagation mechanisms exist as the detonation is propagating in the curved channel.…”
