Abstract:

David Taylor Model Basin Model 5365 RV Athena was chosen by the Office of Naval Research ONR to be used to assess the current state of Computational Fluid Dynamics CFD capability in predicting ship generated wave fields. CFD solutions for two cases were generated by several organizations and submitted to the workshop. The codes and organizations are as follows Das Boot - SAIC, Naval Hydrodynamics Group, La Jolla, CA, Numerical Flow Analysis NFA - SAIC, Naval Hydrodynamics Group, La Jolla, CA and Massachusetts Institute of Technology, CFD SHIP- IOWA, Fluent, and Comet -- NSWCCD, Code 5400, and CFDSHIP-IOWA -- University of Iowa, Iowa Institute of Hydraulic Research. These predictions were compared to measurements of the wave field obtained by NSWCCD, Code 5600. This report will document these comparisons and summarize the results and conclusions of the workshop.
