CFD/EFD Combined methods
SSPA currently lead the ITTC Specialist Committee on Combined CFD/EFD Methods. CFD stands for Computations Fluid Dynamics and EFD stands for Experimental Fluid Dynamics, i.e. model testing. To facilitate the introduction of CFD/EFD Combined Methods in our community, the Committee has identified several research areas which need to be addressed. In this way, they wish to inspire researchers around the world to contribute to the development.
CFD offers new possibilities to improve the EFD based predictions, for example with new treatment of scale effects. On the other hand, we can still not in general rely purely on CFD for ship hydrodynamic predictions for commercial or legal purposes. By using the best combination of CFD and EFD, rather than viewing them as competing methods, we can deliver even better prediction. New methods based on EFD/CFD combinations need to have the same confidence level as the existing recommended procedures give to the end client today.
The International Towing Tank Conference (ITTC) has an important role as a cooperation platform for all towing tank organisations. It gives SSPA, as an active member, an opportunity to influence the worldwide shipping community. The Specialist Committee on Combined CFD/EFD Methods runs from September 2017 to at least September 2020. The Chairman is Dr Sofia Werner from SSPA.

- “In this way, we wish to inspire researchers around the world to contribute to the development. If you are currently studying related topics, or plan to do so, we would very much appreciate if you could inform us about it. Just send me an email!” says Dr Sofia Werner, Manager Strategic Research Hydrodynamics at SSPA.

Seakeeping, fw-factor and combined CFD/EFD methods hot topics at ITTC
ITTC has an important role as a cooperation platform for all towing tank organizations. It gives SSPA, as an active member, an opportunity to influence the worldwide shipping community. At the ITTC’s 28th full conference, the Seakeeping Committee presented a recommended procedure for determining fw, that is largely based on work by our experts. A new Specialist Committee on Combined CFD/EFD methods was decided. The chairman is one of SSPA’s experts.
SSPA - member of The International Towing Tank Conference
ITTC is a voluntary association of worldwide organizations responsible for the prediction of hydrodynamic performance of ships and marine installations. The association is also an observer at the International Maritime Organisation (IMO).
