A New Computational Capability for Ramjet Projectiles
Abstract
A state-of-the-art computer code has been applied to calculate internal and external flows for a ramjet projectile under turbulent, supersonic conditions. A multizone computational approach was used, and its advantages are demonstrated. Two turbulence modeling approaches were tried: 1) The Baldwin- Lomax model applied throughout the flow field; 2) the Baldwin-Lomax model applied outside the backflow regions and a dedicated algebraic k-epsilon backflow model applied within these regions. Comparisons with experimental data shows a significant improvement in the code's predictional capability when the latter approach is used.
