Gabriele Gaiti joined the research group in August 2021. He conducts fundamental research on fluid-structure interactions, focusing on hydrodynamic damping on hydrofoils. Gabriele has developed a circular blade cascade for damping and vibration measurements, enabling the measurement of pressure, velocity, and strain in hydrofoil test sections. Additionally, he is conducting numerical simulations of one-way fluid-structure interactions on hydrofoils. For more detailed information, please visit the dedicated project page.

Johannes Djupesland is a PhD candidate working full-time on the Store2Hydro project. He joined the research group in January 2024, shortly after the project’s inception. Johannes conducts research on reversible pump-turbines, focusing on IEC standard model tests in the Waterpower Laboratory. His work includes the design and optimization of thrusters for model pump-turbines. Johannes is a key contributor to Task 2.1, playing a crucial role in advancing the project’s objectives.

Francesco Albicini is a PhD candidate working full-time on RenewHydro RP1.2 research project. He joined the project in March 2025. Francesco is aimed to study unsteady blade loading during the intermittent operations of the Francis turbine in the laboratory. He will study unsteady pressure loading, strain and stress on the turbine blades. Finally, he will use this data to develop rainflow counting algorithm for the intermittent operations to estimate the fatigue damage on the blades and potential inception of crack on the blades.

Pawan Lal Bijukchhe is a PhD candidate working full-time on RenewHydro RP2.2 research project. He joined the project during August 2025. Pawan is aimed to design and optimize the reversible pump-turbine and the booster pump for the Norwegian hydropower systems. He will use machine learning and other optimization techniques that combines pump-turbine and the booster pump. He will also focus on automated optimization considering the large variability of the hydropower head and discharge.

Øystein Maritssønn Nordmo is writing project and master thesis on transient operation of Francis turbine. Øystein will work in the FME RenewHydro project, and he will focus on particle image velocimetry (PIV) measurements in the vaneless space of the Francis-99 turbine and carry out numerical simulations with dynamic mesh. Øystein aims to move the guide vanes from the part-load to the high load of the Francis-99 turbine in the Waterpower laboratory. Øystein investigate the unsteady flow conditions in the vaneless space that will enable experimental investigations using PIV later.



Aleksander Falkenberg Dokset is currently working on his project and master's thesis, focusing on the transient simulations of the reversible pump-turbine and the thruster. He will investigate the flow conditions in the draft tube during the pump and turbine mode operation. The project work provide important input on the flow conditions in the draft tube and the cavitation performance under different load condition.


Håvard Hernes Leonsen writes project and master's thesis during 2025-26. Håvard will work in a team of store2hydro, where he will focus on developing stationary vanes for dampening the trailing edge vortex from the thruster blades. Håvard will also investigate the flow conditions with stationary vanes during the turbine mode operation.


Edgar Verdijck writes project work during Autumn 2025 under store2hydro, and he is exchange student from TU/e Netherlands. His work is focused on the design of the blades for the thruster using conventional design approach and current state-of-the-art methods.


Ole Martin Fjuk writes master thesis during autumn 2025. The title of the project is "Design and optimization of rim type thruster." Ole Martin Fjuk will work with Gustav Oskar Ludvig Ambj̈ornsson for optimization of the thruster blade however, Ole Martin Fjuk will focus on other optimization methods and automation of the blade profiling and parametrization within computational fluid dynamic simulations.
