Detached-Eddy Simulation (DES) has been applied to various flight conflgurations of a complete C-130H airplane. This work is part of a larger research program in which the over-arching aim is to develop the tools for efficient, accurate, and robust calculation of the turbulent flow around a variety of aircraft at flight conditions. The goals of this work are consistent with the longer-term aims of developing DES as a reliable approach for predicting complex flows of engineering interest. The speciflc objectives of the present investigations have been to use DES to understand the aidlows that influence the airdrop of cargo and parachutists. DES combines the efficiency of a Reynolds-averaged turbulence model near the wall with the fidelity of Large Eddy Simulation (LES) in separated regions. Because of the LES treatment in separated regions, it provides more accurate descriptions of the geometry-dependent, three …
