Abstract
Confirming a conjecture of Lyng–Raoofi–Texier–Zumbrun we show that stability of strong detonation waves in the ZND or smallviscosity limit is equivalent to stability of the limiting ZND detonation together with stability of the viscous profile associated with the component Neumann shock Moreover on bounded frequencies the nonstable eigenvalues of the viscous detonation wave converge to those of the limiting ZND detonation while on frequencies of order one over viscosity they converge to one over viscosity times those of the associated viscous Neumann shock This yields immediately a number of examples of instability and Hopf bifurcation of reacting Navier–Stokes detonations through the extensive numerical studies of ZND stability in the detonation literature
