MEASUREMENTS OF FLOWS OVER AN AXISYMMETRIC BODY WITH VARIOUS APPENDAGES IN A WIND TUNNEL: THE DARPA SUBOFF EXPERIMENTAL PROGRAM

摘要: Pressures, velocities, skin friction, and Reynolds stresses were measured in the stern boundary layer region of an axisymmetric body with and without appendages. The data was used to assess and further develop current computational fluid dynamics (CFD) capability for the prediction of flow fields around underwater bodies. The model configurations tested included an axisymmetric hull, a fairwater, one set of four identical stern appendages, and two axisymmetric ring wings. Analyses of measurement uncertainties of all the measured …
