... Databases A database is an organized collection of data and are often developed using formal design and modeling techniques. Validation and calibration of simulation based design tools requires databases. There are several kinds of databases, depending on the purposes of the final users. For instance, when...

...Hannes Renzsch; Britton Ward . In this paper an approach to mimic the influence of appendages on the pressure distribution on a boat’s hull in RANS simulations is given. While, of course, the appendages could be modelled explicitly in the RANS simulation, this significantly increases the cell count...

... to reduce the computational cost of creating lift and drag force coefficient curves for input into a VPP using both multi-fidelity kriging surrogate modelling and data from existing sail designs. This method is shown to reduce the number of CFD simulations required for a desired accuracy when compared...

... immersed, a reliable hull modeling is necessary to properly simulate the critical transient phases such as touchdowns and takeoffs. The model is a multihull float with a waterline length of 2.5 m. Measurements were made in head waves in both captive and semi-captive conditions (free to heave and pitch...

... of simulations. They illustrate how the rudder angle varies in function of the heel in order to go straight ahead. The heel depends on the sailing conditions (sea state, wind, etc that is why we can observe a heel angle of 15 degrees with a rudder angle of 6 degrees. In this case, the boat is in upwind sailing...

...Anna Ramolini . The design of sails has always been done experimentally, and only recently simulations are starting to be used in the design process. This paper presents a solver that couples CFD and FEM in order to compute the deformed sail shape (flying shape) and the thrust it can provide...

... class yachts is a complex, expensive and time-consuming task. A dynamic velocity prediction program (DVPP) for the AC50 is therefore developed to assess the dynamic stability of different foil configurations and to simulate and optimize maneuvers. The goal 143 is to evaluate certain design ideas...

... method was applied to a 34-foot sailing cruiser and the simulated result showed good agreement with the measured data from full-scale tests; however, the modeling of aerodynamic force variation during tacking was insufficient due to lack of information about the sail forces. In this report, the authors...
