Decaix Jean

Jean Decaix is a Senior academic associate at HES-SO Valais-Wallis, School of Engineering, specializing in hydraulic systems and computational fluid dynamics (CFD). He leads the Hydroelectricity research team and teaches numerical methods at the bachelor level in the Energie et techniques environnementales program. His research focuses on CFD modeling of hydraulic turbines, cavitation dynamics, and pumped storage hydropower flexibility.

Education: BSc in Energy and Production (INP Grenoble, 2009), PhD in Fluid Mechanics (University of Grenoble, 2012). Postdoctoral research at HES-SO Valais (2012–2016).

Key projects include SCCER-SoE (2017–2020) for geothermal and hydropower innovation, and 'SOLUTION DE TRANSFERT D'ENERGIE' (2015–2017) exploring small-scale pumped storage systems. He collaborates with industry partners like EDF and SIG. His work addresses grid stability, turbine flexibility, and numerical methods for hydraulic systems.

Publications span CFD validation, cavitation modeling, and turbine optimization. He participates in interdisciplinary projects like the Indo-Swiss Building Energy Efficiency Project, applying CFD to urban airflow simulations.
