Numerical Modeling Efforts in Support of 3-D Environmental Variability and Acoustic Vector Field Studies
Abstract
The goals of this work were multi-faceted, consistent with the various efforts supported by this work. One aspect was the continued study of the effects of three-dimensional (3-D) environmental variability on propagation and the flow of energy in the acoustic field. This included modeling efforts conducted at URI to support analysis of SW06 data sets in the presence of non-linear internal waves (in collaboration with Prof. Jim Miller of URI and Prof. Mohsen Badiey of UDel). Additional modeling efforts were also expanded to include 2-D and 3-D scattering from rough ocean interfaces and other features (in collaboration with Prof. Mohsen Badiey of UDel), in partial support of data analysis of the KAM08 and KAM11 experiments. In addition, work was conducted to support the PhD (URI) research of Bob Barton (NUWC-Newport) that involved the fundamental analysis of complex vector field scattering from canonical objects (spheres and cylinders). Both theoretical and experimental work was performed and results compared for rigid spheres and cylinders, while numerical modeling was completed for elastic materials. The goal of this effort was to determine if the complex vector intensity contained additional information unique to the scattering from such objects.
