Daniel Valero holds a Civil Engineering degree (Master level) from the Universitat Politecnica de Valencia (Spain), from where he also obtained a Master's Degree in Hydraulic Engineering and Environment. He obtained his PhD at the Universite de Liege (Belgium) and worked in Aachen University of Applied Sciences (Germany) for four years, where he gained experimental and numerical modelling experience on multiphase flows. His main expertise is related to the fluid mechanics of high head hydraulic structures, with a special focus on areas such as air-water flows and energy dissipation. Additionally, his experience with Computational Fluid Dynamics (CFD) dates back to 2011 and, ever since, he has participated in the three-dimensional numerical modelling of: sewers, smooth and stepped spillways, standardized and unconventional energy dissipators, vortex formation in pump intakes, turbulent contaminant transport, and heat transfer; these were oftentimes accompanied by experimental modelling. His works have also advanced knowledge on multiphase flows instrumentation through the use of robust filtering and computer vision techniques.
