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 […]

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 […]
