The Fluid–Structure Interaction (FSI) group at NTNU advances the science and engineering of hydraulic turbines through integrated experimental and high‑fidelity numerical research. We focus on understanding and predicting dynamic loading, fatigue, cavitation, and fluid‑induced vibrations under flexible operating conditions.

The research group, dedicated to the field of hydropower, is driven by a mission "clean energy for all", and the activities are aimed to contribute United Nations Sustainable Development Goals 4, 7, 9 and 13.

Education and students

Education and knowledge sharing are fundamental aspects of our research group, aligning with UN SDG 4: Quality Education. We incorporate real-time research cases into our courses, enabling students to engage with state-of-the-art knowledge in their respective fields. This approach not only enhances their learning experience but also supports their career development.

Research projects

STORE2HYDRO

Store2hydro is Horizon Europe financed project aims to develop novel long-term electricity storage technologies for flexible hydropower. The project focuses on reversible pump-turbine type hydroelectric plants.

RENEWHYDRO

RenewHydro is a large research center in NTNU focusing on conducting research in the field of hydropower. Our group is focusing on design and development of the reversible pump-turbine for retrofitted hydroelectric plants.

BOUNDARY LAYER

Boundary layer is the research project focusing investigation of fluid-structure interaction and boundary layer during resonance. The focus is how hydrodynamic damping and boundary layer reacts to the resonance condition.
