Modelling and numerical simulation for yacht design

Alfio Quarteroni, Nicola Parolini

In the past few years, Computational Fluid Dynamics (CFD) has become an essential tool in the design and optimization of racing sailboats and in particular America's Cup yachts. The prevalent role of CFD in the design process is demonstrated by the number ...

Numerical simulation of free surface incompressible liquid flows surrounded by compressible gas

Jacques Rappaz, Marco Picasso, Alexandre Caboussat

A numerical model for the three-dimensional simulation of liquid-gas flows with free surfaces is presented. The incompressible Navier-Stokes equations are assumed to hold in the liquid domain. In the gas domain, the velocity is disregarded, the pressure is ...

Simulazione numerica per la Coppa America di vela

Alfio Quarteroni, Nicola Parolini

The Ãcole Polytechnique FÃ©dÃ©rale de Lausanne (EPFL) has acted as official scientific advisor for the Alinghi Team, winner of the 2003 Edition of the America's Cup. In this report we discuss the role plaid by mathematical and numerical models in yacht de ...

Synchrotron microangiography with no contrast agent

Giorgio Margaritondo, Amela Groso

Coherent x-rays from synchrotron sources are increasingly used in non-conventional radiological techniques ('phase-contrast' radiology). Our experiments demonstrate that by using white (unmonochromatic) radiation and a time-resolving system, it is possible ...

Computational fluid dynamics for naval engineering problems

Nicola Parolini

The subject of this thesis is the numerical simulation of viscous free-surface flows in naval engineering applications. State-of-the-art numerical methods based on the solution of the Navier-Stokes equations are used to predict the flow around different cl ...

Numerical simulation using RANS-based tools for America's Cup design

Mark Sawley, Nicola Parolini

The application of Computational Fluid Dynamics simulations based on the Reynolds Averaged Navier- Stokes (RANS) equations to the design of sailing yachts is becoming more commonplace, particularly for the America's Cup. Drawing on the experience of the Ec ...

Flow Simulation in an Elbow Diffuser : Verification and Validation

François Avellan, Sebastiano Mauri

Numerical simulation of the unsteady turbulent flow in a three-dimensional draft tube geometry is performed. The investigation is carried out with a commercial finite volume solver implementing the Reynolds averaged Navier-Stokes equations. The modeling of ...

International Association For Hydraulic Research2002

We present a new application of digital holography for phase- contrast imaging and optical metrology. This holographic imaging technique uses a CCD camera for recording of a digital Fresnel off-axis hologram and a numerical method for hologram reconstructi ...

1999

High-performance parallel computer systems have been employed to compute a variety of three-dimensional incompressible fluid flows. Three different numerical methods have been used for the discretization of the Navier-Stokes equations, with domain decompos ...
