Considerations for Bilge Keel Force Models in Potential Flow Simulations of Ship Maneuvering in Waves, a series of unsteady RANS (URANS) computations were performed for the ONR Tumblehome model experiencing large amplitude roll motion at both zero and forward speed conditions, in calm water and in waves.

Roll Damping of a Twin-Screw Vessel: Comparison of RANSE-CFD with Established Methods on Blume’s roll damping measurements. The established methods were developed based on studying results of single-screw ships. It can be concluded that both established methods provide acceptable results in certain ranges. For large roll amplitudes, the established methods are out of range and cannot deliver reliable results.

TEMPEST—A New Computationally Efficient Dynamic Stability Prediction Toolding the dominant nonlinearities within the dynamic stability problem. This paper argues for the efficacy of TEMPEST’s theory in reconciling the need for accurate predictions with computational efficiency.

Study on the Motions and Flooding Process of a Damaged Ship in Wavesf the cruiser and roll RAOs in waves because the center of flood water amidships locates on the starboard side and the flooded water with large free surface area in the upper compartment generates sloshing flow. The developed quasi-dynamic model reproduces these flooding water motion in calm water and waves.

Application of Computing Hydrodynamic Forces and?Moments on a Vessel Without Bernoulli’s Equationover the hull surface into an impulse, the time derivative of several integrals of the velocity potential over the surface of the vessel and possibly the free surface near the vessel is introduced. Some examples of applying the impulsive theory to 2- and 3-dimensional bodies are presented.

Some Results from a New Time-Domain Bilge Keel Force Modelface theory for cases with adequate forward speed with a more conventional approach for cases with zero or low forward speed, using Morison’s equation. This paper presents some representative results from the new bilge keel force model for a surface combatant for various roll amplitudes, roll periods, and forward speeds.
