Jonathan Fahlbeck

Jonathan Fahlbeck is a Visiting Researcher in the Fluid Dynamics department within the Mechanics and Maritime Sciences school at Chalmers University of Technology. His research focuses on low-head pumped hydro energy storage systems, particularly examining the operational characteristics of contra-rotating pump-turbines through both experimental and computational approaches.

Dr. Fahlbeck completed his Doctoral thesis in 2024 titled Flow in contra-rotating pump-turbines at stationary, transient, and cavitating conditions, following a Licentiate thesis in 2022 titled Low head pumped hydro storage with contra-rotating pump-turbines. His educational background demonstrates a specialized focus on renewable energy systems and fluid machinery.

His research interests center on the development and optimization of contra-rotating pump-turbines for low-head applications, with particular emphasis on transient operational behaviors including startup and shutdown sequences, cavitation effects, and variable speed control. His work bridges experimental fluid dynamics with computational modeling to address practical challenges in energy storage systems.

Analysis of his recent publications reveals a clear progression toward increasingly sophisticated investigations of pump-turbine dynamics, with growing emphasis on control strategies, efficiency optimization, and grid integration aspects of low-head pumped hydro storage. His research shows strong alignment with renewable energy integration challenges and grid stability requirements.

Dr. Fahlbeck is a key contributor to the ALPHEUS project (2020-2024), which aims to enhance grid stability through low-head pumped hydro energy utilization and storage, funded by the European Commission. His collaborative work primarily involves researchers Håkan Nilsson and Saeed Salehi within the Fluid Dynamics department at Chalmers.
