Prediction of Resistance and Planing Attitude for Prismatic Planing Hull using OpenFOAM

Numerical Modeling of the Stepped Planing Hull in Calm Water

This article describes a 3D CFD (computational fluid dynamics) simulation implementation of the stepped planning hull in calm water. The turbulent free surface flow around the stepped planing hull is computed with a RANSE method, using the solver ANSYS-CFX. The turbulence model used is standard k–ε. In order to simulate the disturbed free surface, VOF model is implemented. The CFD model has bee...

Development of a Forced Roll Mechanism for Planing Hull Models

A Forced Roll Mechanism was designed and built at the Hydromechanics Laboratory at the United States Naval Academy. The FRM was designed as a dynamometer that forces a planing hull model in roll and measures the resulting roll moment as well as the heave and sway forces. The model is fully restrained in all six degrees of freedom. The dynamometer can be configured to either oscillate the model ...

Performance Analysis and Prediction of High Speed Planing Craft

A comprehensive and critical review of literature pertaining to the study of planing craft is given within this work. This study includes monohull design, analysis and performance prediction for flat water; many features of the planing characteristics, including dynamic stability, the use of stepped hullforms, re-entrant transoms and flow characteristics are detailed. Work on the rough water se...

Results of Tibial sesamoid planing

Oblique slamming, planing and skimming

This paper describes how tangential impact velocities can be incorporated into wellknown impact theories in deep and shallow water. Taking the deep and shallow flows in turn, it is shown how to link the normal impact Wagner and Korobkin theories to the tangential impact theories of planing and skimming respectively. An instability is revealed that limits the configurations that can be analysed ...
