Master thesis projects

Together with Chalmers University Technology, SSPA announces two proposals of Master thesis projects. The current thesis projects that are available are “High-performance sailing: Fluid Structure Interaction of hydrofoils” and “CFD modelling of floating object’s motion decay”. The projects start in January 2021.

High-performance sailing: Fluid Structure Interaction of hydrofoils

With the advent of foiling in the America’s Cup in 2013 and the subsequent interest in foiling, the future of high-performance sailing is pending toward a large portion of foiling boats being sailed and built. The use of composite manufacturing and light-weight structures implies that significant deformations of the hydrofoils are present in all sailing scenarios, leaving the designers to investigate not only the hydrodynamic forces from the shape of the foil, but also its Fluid Structure Interaction (FSI) behaviour. The deflection and twists of the hydrofoils under fluid loads will ultimately affect the stability of the whole boat with implications in the overall speed and crew-safety.

The supervisory team composed of Arash Eslamdoost (Associate Professor –supervisor and examiner, department of Mechanics and Maritime Sciences, Chalmers University of Technology) and Laura Marimon Giovannetti (co-supervisor from SSPA) will provide some real-sailing scenarios and loading cases with the expertise from Laura of high-performance sailing both from an engineering and from a sailing perspective.

CFD modelling of floating object’s motion decay

Ocean wave as a renewable energy source is accessible in many parts of the world. Design of a power take-off (PTO) unit for a wave energy convertor depends on the knowledge of interaction between water surface and solid object. Study of slamming loads and motion of floating object in waves are important both from structural design point of view and from fluid-structure interaction. There are many numerical tools available to simulate the motion of a vessel in water, but the accuracy of simulations and cost of the calculations are always two important factors for the design process. Evaluation of the numerical models against the experimental data is the focus of this study.

The supervisory team composed of Dr Alex A. Shiri (supervisor from SSPA), Carl-Erik Janson (Professor – supervisor, department of Mechanics and Maritime Sciences, Chalmers University of Technology) and Dr Laura Marimon Giovannetti (co-supervisor from SSPA) will provide experimental scenarios, cases of generic bodies and CFD methods to simulate the motion of object.
