Stern Advances Hands-On Learning at UI

Posted on April 15th, 2014

At the University of Iowa, Professor Frederick Stern has developed a customized educational approach using the ANSYS Workbench interface and tools that help students quickly learn to use ANSYS Fluent for advanced computational fluid dynamics (CFD) simulations, while reinforcing introductory and intermediate fluid mechanics concepts.

Posted on November 1st, 2013

CFDShip-Iowa is general-purpose computational fluid dynamics (CFD) simulation software developed at the University of Iowa’s IIHR—Hydroscience & Engineering. CFDShip-Iowa represents, in part, deliverables for sponsored research funding from the Office of Naval Research. The program solves the incompressible Reynolds-averaged Navier-Stokes (RANS) and continuity equations with a variety of turbulence models, and a single-phase level set […]

Wave Basin

Posted on October 28th, 2013

Experiment The new IIHR—Hydroscience & Engineering wave basin facility is described, which was specifically designed for global and local flow measurements around free running models for benchmark CFD validation data, including six plunger-type wave makers, x carriage and y, θ sub-carriage/turntable with the model tracking system, the model release system, and semi-captive mount. Trajectories are […]

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 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 […]

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 […]

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.
