EDUCATION
Fernando Hernández Jiménez started his mechanical engineering studies at the Universidad Carlos III in 2003. After obtaining his degree in 2007 at University Carlos III, he obtained his Master in Thermal and Fluids Engineering in 2009. His formation has continued with several research stays at the ETH Zurich, working with Prof. Christoph R. Müller which continued with an active collaboration. He obtained his Associate Professor position in 2020.

RESEARCH INTERESTS
His research is mainly focused on CFD simulations of fluidized beds, studying its global behaviour and comparing its results with experimental data and theoretical models with the final aim of improving its accuracy and validation.

Currently, he is working in the application of granular system to Energy Storage Systems for CSP applications.
