...E. L. Amromin; B. Metcalf; G. Karafiath Friction on a surface covered by an air cavity is much less than friction in water but there is a resistance penalty caused by the cavity tail oscillations. Nevertheless, there is a method for designing the ship bottom form for suppressing these oscillations...

...Kideok Ro This study was conducted in an attempt to improve the hydrodynamic performance of a Weis-Fogh type ship propulsion mechanism by installing a spring to the wing so that the opening angle of the wing can be changed automatically. With the prototype design, the average thrust coefficient...

...Q. X. Wang; S. K. Tan A slender body of revolution berthing to a wall is studied by extending the classical slender body theory. This topic is of practical importance for a ship berthing to a quay wall. The flow problem is solved analytically using the method of matched asymptotic expansions...

...Tao Xing, Ph.D.; Pablo Carrica, Ph.D.; Frederick Stern, Ph.D. A procedure is proposed to perform ship hydrodynamics computations for a wide range of velocities in a single run, herein called the computational towing tank. The method is based on solving the fluid flow equations using an inertial...

... influenced by the cavity topology. The change in cavity shape was determined by loading and not by the sweep angle. Cavitation has been extensively tested in the past on two-dimensional hydrofoils (i.e., Franc and Michel ( 6 )). However, cavitation on ship propellers is distinctly three dimensional due...

...J. Longo; J. Shao; M. Irvine; F. Stern Phase-averaged organized oscillation velocities ( U , V , W ) and random fluctuation Reynolds stresses ( u u ¯ , v v ¯ , w w ¯ , u v ¯ , u w ¯ ) are presented for the nominal wake of a surface ship advancing in regular head (incident) waves, but restrained...

...Kideok Ro; Baoshan Zhu; Hokeun Kang The velocity and pressure field of a ship’s Weis-Fogh-type propulsion mechanism are studied in this paper using an advanced vortex method. The wing (NACA0010 airfoil) and channel are approximated by source and vortex panels, and free vortices are introduced away...

..., Part 2 of this two-part paper provides an example case study following the recently developed comprehensive verification and validation approach presented in Part 1. The case study is for a RANS simulation of an established benchmark for ship hydrodynamics using a ship hydrodynamics CFD code...
