Computational Hydrodynamics and Control Modeling for Autonomous Underwater Vehicles

摘要

The long term objective of the program is to develop predictive technologies to support virtual design and evaluation of underwater vehicles systems. CFD technologies will be used to protect hydrodynamic models for AUVs and those models will be coupled with control system design and modeling tools to allow vehicle conceptual design to be evaluated within the context of a realistic mission. The objectives of this effort were to compare the forces and moments acting on a maneuvering AUV predicted by computational fluid dynamics (CFD) code with similar data collected aboard an operational AUV. In particular, the multi-block Navier-Stokes flow solver UNCLE (Unsteady Computational of Field Equations) was used in this effort.
