WebJan 1, 2010 · The latter, commonly referred to as 'cook off', has been widely studied and contemporary kinetic and transport models accurately predict time and location of ignition for simple geometries. However, there has been relatively little attention given to the problem of localized ignition that results from the first three ignition sources of impact ... WebThe condensed phase HMX decomposition reactions are described by distributed kinetics. The gas phase description includes a detailed chemistry model for the combustion of HMX. Results are presented that outline considerations for simulating fast cook-off ignition. It is found that small changes in the heat path, such as air gaps, significantly ...

Considerations for Fast Cook‐Off Simulations - Gross
WebMORE In order to investigate thermal response of explosive at fast cook-off environment, the fast cook-off tests for GHL explosive, subjected to external fire scenario, were carried out. The ignition time was measured. A thermal reaction model of GHL explosive was established. The external flame flow and decomposing heat of explosive were ...

We present a simple idea to simulate dynamic fracture and fragmentation of a propulsion system exposed to an extreme condition, such as a fire. The system consists of energetic materials confined in a steel cylinder. The strain failure model of the confinement is a modified Johnson-Cook model with a statistical failure distribution. tracer watches in the usa
