AWAC used for ship wake studyThe Acoustic Surface Tracking (AST) capability of the AWAC was used for a comprehensive ship wake study by engineers at the Naval Surface Warfare Center, USA.

Engineers at the Naval Surface Warfare Center, Carderock Division, used the AST capability on the AWAC to measure various characteristics of the breaking wave generated from a submerged ship transom.

The primary objective of this work was to obtain full-scale qualitative and quantitative flow field data of a large breaking transom wave over a range of conditions, specifically transom drafts and Froude numbers.

Results from the experiment are presented in the proceedings of the 2008 ASME Fluids Engineering Conference.
