Streszczenie:

The transom stern offered some advantages over the traditional rounded cruiser stern reducing the resistance of a ship. This can only be achieved if the transom stern is carefully designed with suitable transom immersion ratio. In this study, the influence of different transom area immersion ratios on the resistance components was investigated for a semi-displacement hull and a full displacement hull. The base hull was based on NPL hull form and KCS hull form for a semi-displacement and full-displacement hull respectively. The transom immersion ratios for the NPL hull were varied at a ratio of

Measurements of the free-surface behind a backward facing step are made using laser-induced fluorescence and a digital video camera. Tests are conducted for two Reynolds numbers and a range of Froude numbers. An edge detection algorithm is used to locate the free surface from the digital images, and the ensemble of images are used to calculate the mean and root mean square of the elevation. The results of amplitude, length, and steepness are determined from the mean profiles and compared to existing potential flow theories. It is found that the potential flow theories overpredict the real-flui

We present a model for the fast evaluation of the total drag of ship hulls operating in both wet and dry transom stern conditions, in calm or wavy water, based on the combination of an unsteady semi-Lagrangian potential flow formulation with fully nonlinear free-surface treatment, experimental correlations, and simplified viscous drag modeling. The implementation is entirely based on open source libraries.

The steady wave patterns, Kelvin-wake spectra and wave resistance of several realistic ship hulls are computed by a Rankine panel method. Wall-sided as well as transom-stern ships are studied over a broad range of Froude numbers and the importance of enforcing a Kutta-type condition of smooth flow detachment at the transom stern is demonstrated. The lack of numerical damping in the solution scheme permits the reliable prediction of the Kelvin wake far from the ship and allows its use in the evaluation of the free wave spectrum. The wave resistance is evaluated by pressure integration as well a

Ship performance improvements such as delivered power reduction and fuel savings, and maximum speed increases, have been proven during at-sea trials and are well documented (Cusanelli 2002).

The renovation related to technical design factors, while it is still not yet be reviewed. This study aims to identify and compare differences in technical design factors between the aid vessel and the local vessel. Identification method by direct observation, including measurements of the main dimensions, shape of the hull and bow, general arrangement and working area. The identification data is compared to get t

We analyse the turbulence characteristics and consider the closure modelling of the air entraining flow in the wake of three-dimensional, rectangular dry transom sterns obtained using high-resolution implicit large eddy simulations (iLES) (Hendrickson et al., J. Fluid Mech., vol. 875, 2019, pp. 854–883). Our focus is the incompressible highly variable density turbulence (IHVDT) in the near surface mixed-phase region ${\mathcal{R}}$ behind the stern. We characterize the turbulence statistics in ${\mathcal{R}}$ and determine it to be highly anisotropic due to quasi-steady wave breaking. Using un

In this paper, the application of the excessive acceleration (EA) criterion, one of five intact stability failure modes, within the second generation intact stability criteria (SGISC) framework, is shown for a set of naval vessels. First and second level vulnerability assessment of the criterion is applied to parent hulls D1 and D5 of D-Systematic Series, the US Office of Naval Research (ONR) Topside Series model, and the European multi-purpose frigate FREMM. All of which are semi-displacement, transom stern, and round bilge hull forms. Relatively low ship roll periods and great variations of

Ride control systems are essential for comfort and operability of high-speed ships, but it remains an open question what is the optimum ride control method. To investigate the motions of a 112-m high-speed catamaran fitted with a ride control system, a 2.5-m model was tested in a towing tank. The model active control system comprised two transom stern tabs and a central T-Foil beneath the bow. Six ideal motion control feedback algorithms were used to activate the model scale ride control system and surfaces in a closed-loop control system: heave control, local motion control, and pitch control

Computational fluid dynamics (CFD)-based optimization of a surface combatant is presented with the following main objectives:development of a high-performance optimization module for a Reynolds averaged Navier-Stokes (RANS) solver for with-free-surface condition; anddemonstration of the capability of the optimization method for flow- and wave-field optimization of the Model 5415 hull form. The optimization module is based on extension of successive quadratic programming (SQP) for higher-performance optimization method by introduction of parallel computing architecture, that is, message passing
