We investigate hydrodynamic instability of a steady planar detonation wave propagating
in a circular tube to three-dimensional linear perturbations, using the normal
mode approach. Spinning instability is identified and its relevance to the well-known
spin detonation is discussed. The neutral stability curves in the plane of heat release
and activation energy exhibit bifurcations from low-frequency to high-frequency spinning
modes as the heat release is increased at fixed activation energy. With a simple
Arrhenius model for the heat release rate, a remarkable qualitative agreement with
experiment is obtained with respect to the effects of dilution, initial pressure and
tube diameter on the behaviour of spin detonation. The analysis contributes to the
explanation of spin detonation which has essentially been absent since the discovery
of the phenomenon over seventy years ago.
