Welcome to the Institute of Fluid Dynamics and Ship Theory (FDS) at TUHH

At the Institute of Fluid Dynamics and Ship Theory (FDS), we are dedicated to advancing knowledge in naval architecture as well as engineering and geophysicalfluid dynamics, tackling complex challenges in a wide range of applications, including ship manoeuvring, dynamic stability of surface and underwater vessels, cavitation, propulsion, underwater noise emissions, offshore wind farms and green hydrogen technologiesas well as wind-wave interaction, ship-ice interaction, mathematical shape optimization, ditching of aircraft or medical technology. Our research is at the intersection of engineering and environmental applications, driving innovation in maritime and renewable energy sectors.

Our international and renowned team combines expertise in theoretical analysis, physical modeling, the development of advanced numerical methods and complex multiphysics simulations.

We specialise in applying this expertise to the development of innovative flow simulation codes. This enables us to investigate the intricate fluid dynamic behaviour of non-linear systems and processes. This multidisciplinary approach ensures that our research contributes to fundamental scientific advancements as well as practical engineering solutions.

FDS is equipped with state-of-the-art computational and experimental facilities, allowing us to conduct high-quality research and collaborate on major projects funded by the German government and the European Union. Our researchers work closely with leading industry partners in shipbuilding, marine engineering, aerospace, automotive, medicine and renewable marine energy, ensuring that our innovations have real-world applications and impact.

🚢 Students are encouraged to participate in our courses and engage in research projects that provide hands-on experience in fluid dynamics and ship theory.
🤝 Industrial partners are warmly invited to explore collaboration opportunities and benefit from our expertise in cutting-edge maritime research.

Join us in shaping the future of sustainable maritime and fluid engineering technologies!

In August and September, members of the FDS institute travelled to Asia to take part in two international workshops and present their current research. The 13th International Workshop on Ship and Marine Hydrodynamics (IWSH) was held in Fukuoka, Japan, where we had the opportunity to connect with researchers working in the fields of Computational Fluid Dynamics, Seakeeping and Propulsion, and learn about the latest advancement in their work. We are especially proud to share that Lukas Altenbach received the Best Student Paper Award for his work on 'An efficient approach to CFD simulations with small  ships manoeuvring in the wave field of larger ships via optimized forcing zones'. In his study, he presents a numerical method for modeling the ship-ship interaction between a tugboat and a cargo vessel using a one-way coupling approach. By prescribing the wave field generated by the larger ship as boundary conditions for the smaller one by adapting Forcing Zones, the method reduces the computational effort required to simulate the maneuvering behavior of the smaller vessel when investigating multiple scenarios. Congratulations on this achievement, Lukas! Our next stop was Shanghai, China, where we participated in the International Workshop on Ship Propulsion and Hydrodynamics (IWSPH). A highlight of the trip was the visit at the China Ship Scientific Center (CSSRC) in Wuxi. We are very grateful for not only the academic exchange, but also for the smooth organization, warm welcome, and generous hospitality we experienced during our stay!
