1. Dynamic effects on yacht sails and rudders
Abstract : In search of increased performance, modern sailing vessels are becoming more and more complex, introducing additional challenges in the design process. The dynamic behaviour of the vessel is of great importance to safe and efficient operation and thus needs to be accounted for when evaluating the performance. READ MORE

2. Potential Flow Panel Methods for the Calculation of Free-surface Flows with Lift
Abstract : Two non-linear Rankine-source panel methods are developed and implemented in the same computer code. The first method uses a four-point upwind operator on the free-surface to compute the velocity derivatives and to enforce the radiation condition while the second method uses an analytical expression for the velocity derivatives and a collocation point shift one panel upstream to prevent upstream waves.

3. Strongly Coupled Performance Prediction for Sailing Yachts based on CFD
Abstract : Quantifying performance of sailing yachts can be done in many different ways. Historically the most common way is a static approach where a steady state solution is obtained by solving equilibrium equations in 3 or 4 degrees of freedom. More recently, dynamic methods have appeared. In this thesis a method of the latter kind in proposed. READ MORE

4. Computational hydrodynamics applied to an America's Cup class keel - best practice and validation of methods
Abstract : Numerical predictions of the flow around yacht keels can be performed with various types of methods. In this work computational fluid dynamic (CFD) computations are validated against wind tunnel studies of an America's Cup Class keel with the purpose of investigating the accuracy that can be achieved with CFD, which methods that are suitable and how they should be used in the best way.
