5512 Steady

Posted on September 10th, 2013

Experiment Results from towing tank experiments for David Taylor Model Basin model 5512 are presented for resistance, sinkage and trim, wave profile, and nominal wake tests and uncertainty assessment. Model 5512 is a 1:46.6 scale, 3.048 m long, fiber reinforced Plexiglas hull, which is a geosim of DTMB model 5415, a 1:24.8 scale 5.72 m model.

5512 Roll Decay

Posted on September 10th, 2013

Experiment Towing-tank experiments are performed for an advancing surface combatant in free roll decay motions. Results are presented for motions (surge, sway, heave, roll, pitch and yaw), forces (resistance, sway and heave), moments (pitch and yaw), phase-averaged velocities (U, V and W) for a measurement region near the bilge keel and free surface elevations.  The geometry of interest is DTMB […]

5512 Pitch and Heave

Posted on September 10th, 2013

Experiment Towing-tank experiments of coupled pitch and heave motions are presented for a surface combatant advancing in regular headwaves.  The data includes ballasting parameters, encounter frequency, time histories, Fourier series amplitudes, and pitch and heave transfer functions and phase. The geometry of interest is DTMB model 5512, a 1:46.6 scale, 3.048 m long, fiber reinforced […]

5512 Forward Speed Diffraction

Posted on September 10th, 2013

Experiment Results are presented from towing-tank tests of forces and moment, wave elevation, and phase-averaged nominal wake velocities and Reynolds stresses for a surface combatant advancing in regular head waves, but restrained from body motions, i.e., forward-speed diffraction problem. The geometry is DTMB model 5512, a 1:46.6 scale, 3.048 m long, fiber reinforced Plexiglas hull. […]

Flat Plate

Posted on August 28th, 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, […]

IIHR has a long and illustrious history of ship hydrodynamics research, which began in earnest in 1954 when Lou Landweber came to the institute from his leadership role at the David Taylor Model Basin. According to an account in Flowing Through Time: A History of the Iowa Institute of Hydraulic Research, by Cornelia F. Mutel, […]

Stem to Stern: Revolutionizing Ship Hydrodynamics

Posted on August 1st, 2013

For 17-year-old Fred Stern, the future looked bright from the deck of a sailboat racing across the waters of Lake Ontario. The young man from Syracuse, N.Y., took advantage of his home’s close proximity to the Great Lakes to spend every moment he could sailing. With a small push from his father, Stern channeled his […]
