Interior ballistics flows of conventional charges in gun tubes
possess complex flow pattes. Their complexity is due to both the
heterogeneous structure of the charge and the rapidly changing flow
conditions within a few milliseconds. The fast rise in pressure and
temperature caused by the buing of the propellant initiates a
turbulent, multidimensional, multiphase flow which is coupled with
the accelerating projectile motion. A complete mathematical model
that describes all the physical phenomena occurring in an interior
ballistics cycle is not presently available. However, several
models that simulate some of the phenomena exist or are being
developed.
