Abstract

Delayed Detached-Eddy Simulation (DDES) has been applied to various configurations of a simplified C-130 wind tunnel model. This research represents a continuation of work to determine the flow-field characteristics of the C-130 Hercules aircraft as part of the NATO supported Airflow Influence on Airdrop (AIA) project. The models include both closed and open cargo door configurations, and both the simulations and experiments use the same Computer-aided design (CAD) geometries. A combined grid-resolution and time-step sensitivity study was performed for each geometry and serves to ensure the numerical simulations are accurate for the separated flows. Excellent agreement is found between experiments and DDES simulations for vortex location, strength and orientation, and the DDES results are shown to compare more favorably than previous Detached-Eddy Simulation (DES) results for these configurations.
