PBX 9502 Failure Diameter: Addendum
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
In previous reports, the SURFplus reactive burn model was used to study a propagating detonation wave for PBX 9502 in an unconfined rate stick just above the failure diameter. Simulations showed that the sonic boundary condition at the HE interface leads to a boundary layer. Here we provide additional details on the steady-state flow with emphasis on the boundary layer. This confirms the previous conclusion that within the boundary layer the lead shock, which initiates the hot-spot reaction, is largely supported by transverse energy flow in the reaction zone from the interior towards the boundary. Consequently, the reactive wave along a boundary layer streamline does not correspond to a 1-D detonation wave in the sense of detonation shock dynamics; i.e., the lead shock which initiates the reaction is not driven by the reaction energy along the streamline.
