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 predict hydrodynamic models for AUVs and those models will be coupled with control system design and modeling tools to allow vehicle conceptual designs to be evaluated within the context of a realistic mission. Use of these technologies will reduce the cost associated with experimental testing and the evaluation of a larger number of design options will result in vehicle systems with better overall performance. The next phase in the development of these capabilities is to extend the capabilities of the CFD technologies to enable modeling of AUVs in very shallow water. Models for the dynamic environment including bottoms and free-surface with waves have already been developed and need to be coupled with the vehicle models described in this report. Basic and applied research will be required to characterize the operation of AUVs in this environment for the purpose of performance assessment since existing reduced-order model formulations are not applicable.
