Maneuvering Predictions for Submarine Configurations

Abstract

Under a prior research effort entitled, "Flow Around Maneuvering Appended Bodies" the NSF Engineering Research Center at Mississippi State (MSU/ERC) and the Applied Research Laboratory at The Pennsylvania State University (ARL) developed a physics-based means of predicting the maneuvering characteristics of a self-propelled, fully-appended underwater vehicle. Subsequently, a follow-on project to extend the Initial capability was undertaken. This addresses many of the issues that remained at the conclusion of the original project Specific areas being addressed include: (1) computation of flow at very high (full-scale) Reynolds number, (2) investigation of different grid topologies, (3) turbulence models studies, (4) effective use of parallel processing, and (5) depth-changing maneuvers. Subsequently, the follow-on effort was divided into two parts to allow consideration of classified configurations under a separate project.
