Accurate Flow Prediction for Store Separation from Internal Bay
Abstract
Accurate prediction of store separation from internal aircraft bays is of great importance in commercial and military aircraft design. The flow-field inside and over the bay is very complex, especially for supersonic flows involving shock-boundary layer interaction, compressible shear layer, and strong acoustics. Understanding the physics of the flow in and surrounding the bay is of great importance for safe release of stores and controlling the acoustic environment. The supersonic flow-field within and surrounding the bay is unsteady, and accurate prediction of the shear layer requires dynamic simulations with advanced numerical and physical models. The objective of this paper is to demonstrate accurate prediction of the effect of the flow and a control method by employing a turbulence model that is not cost-prohibitive and is accurate enough to simulate such complex flow phenomena. The turbulence model employed for this study is a two-equation hybrid Reynolds-Averaged Navier-Stokes (RANS) [1] and Large Eddy Simulation (LES) [2] formulation known as the Large Eddy Stress balanced (LESb) model [3].
