FIG. 1.

A planar thin detonation front travels with velocity through a nonuniform mono-modulated density field. A set of vortical, entropic, and acoustic perturbations is generated downstream.

FIG. 2.

Detonation front evolution for / = 0.3357 (left-hand-side plot) and / = 0.5035 (right-hand-side plot) as obtained with γ = 1.2, = 10, and = 2 from (A13) (solid curves) and from (23b) (dashed curves).

FIG. 3.

The variation with the incident angle θ = tan ( / ) of the amplitudes of the permanent solution for γ = 1.2, = 10, and = (0, 1, 2, 5, 10), with the grey tone used for each curve progressing from darkest ( = 0) to lightest ( = 10) as the exothermicity increases.

Image of FIG. 4.
FIG. 4.

The variation with the propagation Mach number of the peak amplitude of the permanent solution at ζ = 1 for γ = 1.2 and = (0, 1, 2, 5, 10), with the grey tone used for each curve progressing from darkest ( = 0) to lightest ( = 10) as the exothermicity increases and with dashed and solid curves employed for / < 3 and / > 3, respectively.

Image of FIG. 5.
FIG. 5.

Detonation response to isotropic density disturbances as a function of the Mach number for γ = 1.2 and = (0, 1, 2, 5, 10), with the grey tone used for each curve progressing from darkest ( = 0) to lightest ( = 10) as the exothermicity increases.

FIG. 6.

The integration domain in the (, τ) plane including the detonation trajectory = τ, the characteristics lines (dashed lines), and the particle paths (thick dotted lines) with indication of regions of perturbed and unperturbed flow.
