Hull-form optimization in calm and rough water
نویسندگان
چکیده
The paper presents a formal methodology for the hull form optimization in calm and rough water using wash waves and selected dynamic responses, respectively. Parametric hull form modeling is used to generate the variant hull forms with some of the form parameters modified, which are evaluated in the optimization scheme based on evolutionary strategies. Rankine-source panel method and strip theories are used for the hydrodynamic evaluation. The methodology is implemented in the optimization of a double-chine, planing hull form. Furthermore, a dual-stage optimization strategy is applied on a modern fast displacement ferry. The effect of the selected optimization parameters is presented and discussed.

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...

Since 1994 the Australian Maritime Engineering Cooperative Research Centre (AME CRC) has conducted an extensive set of towing tank experiments and theoretical predictions for calm and rough water, on a series of 11.3 metre IMS style racing yacht hulls with varying form parameters. In collaboration with Murray, Burns & Dovell (MBD), the AME CRC has developed a Velocity Prediction Program (VPP), ...

So far many case-study researches have been undertaken to propose suitable models for hull optimization of planning high-speed crafts. In this paper a systematic and generic method is illustrated for the first time to introduce the optimized hull form of craft considering the desired speed and weight. Using semi-empirical Savitsky's method, optimal geometrical parameters of planning high-speed ...

Although catamaran configuration has been around for a longtime, it is only in the recent past that such hull forms have seen unprecedented growth in the high-speed ferry industry. One of the design challenges faced by naval architects is accurate prediction of the hydrodynamic characteristics of such vessels primarily in the areas of resistance, propulsion and seakeeping. Even though considera...
