Abstract
The propellant gas flow behind a projectile inside of a tube weapon is investigated numerically. The main subject is coupled to the viscosity related phenomena such as boundary layer formation, turbulence and heat transfer to the wall. Therefore, the full Navier-Stokes equations are used to describe the gas flow. Different kinds of turbulence models are implemented. Comparisons with experimental results are performed. The DELTA code is used as the basis for the numerical simulation and extended properly for turbulence and heat transfer. Several numerical results are presented. Fundamental thoughts on the numerics are added.
