A blunt and streamlined submersible object was experimentally tested in a tow tank and openwater channel to measure the hydrodynamic characteristics of its performance. Models were ran at3 primary speeds, submergences, and size scales to investigate effects on the resistance, seakeeping,and wake flow field of the model. Experimental measurements collected include dynamic forcesand torques, pressures, generated wave fields, velocity and vorticity measurements using a ParticleTracking Velocimetry system, point velocity measurements using an Laser Doppler Velocimetrysystem, and fluorescein dye visualizations.Objectives for this study are to better understand bluff body flow and potential improvementsthat can be made to enhance the performance of underwater or surface vessels. Negative characteristics may include unsteady forces causing the vessel to rise or sink, exorbitant drag productionnear the blunt bow or transom stern which dramatically increase the powering requirements, andunsteady flow structures generated that produce unwanted effects on the body. These issues areimproved by attaching streamlined fairings to the front and rear of the model which decrease thelarge resistance and unsteady forces experienced.Overall, this study found that the streamlined design produces an overall reduction in resistance and negative flow characteristics given its reduced form drag as opposed to the blunt model.The streamlining allows the flow at the front and rear to naturally follow the body's curvatureand not become trapped in various flow structures such as boundary layer separation or vortexes.Additionally, the streamlined design exhibits improved performance in nearly all other aspects ofthis research.
