Abstract:

In the accelerating flow of a lighter continuous phase through a heavier one, small non-uniformities grow into large ones due to the Rayleigh-Taylor Instability. An experiment exemplifying the large bubble formation due to Rayleigh-Taylor Instability has been performed and simulated using the PHOENICS 84 computer code. The same numerical procedure was applied to the two-phase flow in a gun barrel. It showed that the acceleration provided by the movement of the projectile can cause initial non-uniformities to grow with time.
