Secondary Combustion in Gun Exhaust Flows
Abstract
The muzzle flash from cannon is analyzed using a simple description of the gun exhaust plume flow structure coupled to an empirical ignition criteria. The effect of muzzle devices such as recoil brakes is estimated through an approximate description of their internal flow. The influence of the transient nature of the weapon exhaust plume is examined by using a one- dimensional, unsteady numerical model to develop the flow properties along the axis of symmetry. These properties are input into the ignition model and the possibility of the occurrence of secondary combustion is determined as a function of time during gun tube emptying.
