Impulsive Plunging Wave Breaking

Posted on October 28th, 2013

Experiment The plunging wave-breaking process for impulsive flow over a bump in a shallow water flume is described, which is relevant to ship hydrodynamics since it includes the effects of wave-body interactions and the wave breaking direction is opposite to the mean flow. Phase averaged measurements (relative to the time at which the maximum wave […]

Series 60 Steady Flow

Posted on September 10th, 2013

Equipment Results are presented from a towing-tank experiment conducted in order to explicate the influence of wavemaking by a surface-piercing body on its boundary layer and wake and provide detailed documentation of the complete flow field appropriate for validating computational fluid dynamics methods. Mean velocity and pressure field measurements were performed for two Froude numbers, 0.16 […]

Series 60 Propeller Hull Interaction

Posted on September 10th, 2013

Experiment Results are presented from a towing-tank experiment of propeller-hull interaction conducted in order to provide detailed documentation of the complete flow field appropriate both for explicating the flow physics and validating computational methods.  Mean-velocity and pressure field measurements were made for the with- and without-propeller conditions for the Series 60 CB=0.6 hull form at numerous […]

Series 60 Drift

Posted on September 10th, 2013

Experiment Yaw effects on model-scale ship flow are documented through towing-tank experiments for a 3.048-m Series 60 CB=0.6 model ship.  The data includes: photographs and video; resistance, side force, and yaw moment; sinkage, trim, and heel; wave profiles along the hull and wave elevations; and mean-velocity and pressure fields for numerous crossplanes from the bow […]

NACA24

Posted on September 10th, 2013

Experiment Results are presented from a towing-tank experiment of 3D separation and free-surface turbulence to provide detailed documentation of the flow appropriate both for explicating the flow physics and validating computational methods.  The model is NACA24 which is a 1.2 m chord length, vertical, surface-piercing hydrofoil.  The data includes far and near field wave elevations, surface […]

5512 Captive Maneuvering

Posted on September 10th, 2013

Experiment Towing-tank experiments are performed for a surface combatant as it undergoes static and dynamic planar motion mechanism maneuvers in calm water. The data includes global forces/moment/motions and phase-averaged local flow-fields, and uncertainty assessment. The geometry is DTMB model 5512, a 1:46.6 scale, 3.048 m long, fiber reinforced Plexiglas hull. Model 5512 is a geosim […]
