The Numerical Simulation of Ship Waves using Cartesian Grid Methods
Mark Sussman, Douglas G. Dommermuth
Two different cartesian-grid methods are used to simulate the flow around the DDG 5415. The first technique uses a "coupled level-set and volume-of-fluid" (CLS) technique to model…
A Numerical Formulation for Simulating Free-Surface Hydrodynamics
Thomas T. O'Shea, Kyle A. Brucker, Douglas G. Dommermuth +1
Cartesian-grid methods in combination with immersed-body and volume-of-fluid methods are ideally suited for simulating breaking waves around ships. A surface panelization of the sh…
Numerical Simulation of Wakes in a Weakly Stratified Fluid
James W. Rottman, Douglas G. Dommermuth, George E. Innis +2
This paper describes some preliminary numerical studies using large eddy simulation of full-scale submarine wakes. Submarine wakes are a combination of the wake generated by a smoo…
The Numerical Simulation of Ship Waves Using Cartesian Grid Methods with Adaptive Mesh Refinement
Douglas G. Dommermuth, Mark Sussman, Robert F. Beck +4
Cartesian-grid methods with Adaptive Mesh Refinement (AMR) are ideally suited for simulating the breaking of waves, the formation of spray, and the entrainment of air around ships.…
The Numerical Simulation of Ship Waves Using Cartesian-Grid and Volume-of-Fluid Methods
Douglas G. Dommermuth, Thomas T. O'Shea, Donald C. Wyatt +5
Cartesian-grid methods in combination with immersed-body and volume-of-fluid methods are ideally suited for simulating breaking waves around ships. A surface panelization of the sh…
An Integrated Experimental and Computational Investigation into the Dynamic Loads and Free-surface Wave-Field Perturbations Induced by Head-Sea Regular Waves on a 1/8.25 Scale-Model of the R/V ATHENA
Toby Ratcliffe, Lisa Minnick, Thomas T. O'Shea +3
A 1/8.25 scale-model of the U.S. Navy Research Vessel ATHENA was tested in regular head-sea waves to obtain data for validation of computational fluid dynamics (CFD) predictive too…
An Experimental and Computational Study of Breaking Wave Impact Forces
Thomas C. Fu, Anne M. Fullerton, Susan Brewton +2
The impact forces generated by the impact of a breaking wave are poorly understood. These impulsive hydrodynamic loads to a ship's hull are of short duration relative to ship motio…
A Detailed Assessment of Numerical Flow Analysis (NFA) to Predict the Hydrodynamics of a Deep-V Planing Hull
Thomas C. Fu, Thomas T. O'Shea, Carolyn Q. Judge +3
Over the past few years much progress has been made in Computational Fluid Dynamics (CFD) in its ability to accurately simulate the hydrodynamics associated with a deep-V monohull…
A Comparison of Model-Scale Experimental Measurements and Computational Predictions for a Large Transom-Stern Wave
David A. Drazen, Anne M. Fullerton, Thomas C. Fu +8
The flow field generated by a transom stern hull form is a complex, broad-banded, three-dimensional system marked by a large breaking wave. This unsteady multiphase turbulent flow…
Parameterization of the Near-Field Internal Wave Field Generated by a Submarine
James W. Rottman, Kyle A. Brucker, Douglas Dommermuth +1
We attempt to gain some insight into the modeling of the generation of internal waves produced by submarines traveling in the littoral regions of the ocean with the use of high fid…
A Comparison of Measured and Predicted Wave-Impact Pressures from Breaking and Non-breaking Waves
Anne M. Fullerton, Thomas C. Fu, Susan Brewton +3
Impact loads from waves on vessels and coastal structures are complex and may involve wave breaking, which has made these loads difficult to estimate numerically or empirically. Re…
A Comparison of Full-Scale Experimental Measurements and Computational Predictions of the Transom-Stern Wave of the R/V Athena I
Donald C. Wyatt, Thomas C. Fu, Genevieve L. Taylor +5
Full-scale experimental measurements and numerical predictions of the wave-elevation topology behind a transom-sterned vessel, the R/V Athena I, are compared and assessed in this p…
