Abstract
The compressible, viscous, turbulent gas expansion flow behind an accelerating projectile moving in a gun tube is investigated. Turbulence is described by two algebraic models and by a one-equation model. Comptutational results obtained by application of these models are compared to experimental data obtained with two low pressure gun simulators. Also results are reported for the flow behind a projectile under more realistic interior ballistic conditions.
