Muzzle Flash Onset: An Algebraic Criterion and Further Validation of the Muzzle Exhaust Flow Field Model

摘要

In this report an algebraic criterion to predict the onset of muzzle flash is formulated. The criterion is derived from the detailed analysis of a complex Muzzle Exhaust Flow Field (MEFF) model which includes turbulence and detailed chemical kinetics. The algebraic criterion, therefore, contains the essential features of the complex MEFF model. Additional efforts required for the improvement of the criterion are discussed.
