Critical diameter for stationary detonation in a high density explosive: shell effects
A critical-diameter theory is proposed, based on certain assumptions about the nature of the detonation wave, the conditions in the region of the shock-wave front, and the shape of the front of the detonation wave. The flow in the reaction zone at the axis is examined in order to determine the limiting condition for stationary propagation of a self-maintaining detonation with a curved front. A small part of the shock front near the axis is represented as a spherical surface with a given radius. The conditions for stationarity in the front shape are considered. The model is tested by performing a quantitative analysis of an expression for the critical diameter for charges without shells. Finally, the constraints on this approach are considered.
