Prof. David Le Touzé

Some insights on SPH theories, and key aspects of application to complex free-surface flows

David Le Touzé is deputy director of the Research Laboratory in Hydrodynamics, Energy and Atmospheric Environment (LHEAA) at Ecole Centrale de Nantes and leader of the H2i (Hydrodynamics, Interfaces and Interactions) group. Within that group, he is responsible for activities on fast dynamics flows and multi-physics couplings, and various projects for public research, the navy, and the oil and gas industry. He has worked extensively on the SPH method in engineering, from fundamental development to massively parallel industrial applications. From 2010 to 2015 he was the chair of SPHERIC. In 2015 he received the inaugural Joe Monaghan Prize, along with collaborators, for theoretical work on the treatment of the free surface in SPH.

Dr. Natasha Flyer

Radial Basis Function-Generated Finite Differences (RBF-FD): New Opportunities for Applications in Scientific Computing

Since 2003, Natasha Flyer has been a computational mathematician at the US National Center for Atmospheric Research, with a focus on furthering understanding in the geo- and solar sciences through different aspects of numerical algorithm development. Her work encompasses formulating novel numerical approaches for modeling physical phenomena to benchmarking computational efficiency against state-of-the-art codes to ensuring suitability of the developed novel numerics for high-sustained performance on advanced accelerator architectures. Her primary focus has been on radial basis function-generated finite differences (RBF-FD), a novel local numerical methodology for approximation whose algorithmic simplicity is independent of dimension and geometry. Recently, she has oriented her attention to the potential of combining RBF-FD with machine learning algorithms that would accelerate model prediction. To date her areas of application modeling have been: solar corona, atmospheric electricity, mantle convection, weather, and turbulence.

Prof. Stefan Hickel

Prof. Stefan HickelWhither European Research Community On Flow, Turbulence And Combustion?

Stefan Hickel is Professor of Computational Fluid Dynamics and Chair of Aerodynamics at the Faculty of Aerospace Engineering of TU Delft. He obtained his PhD from TU Munich for research into the design of consistent numerical methods and turbulence models for large-eddy simulation in 2008 and was appointed full professor at TU Delft in 2015. Professor Hickel and his students develop models and methods for high-performance computational thermo-fluid dynamics with which they perform numerical experiments on a broad range of turbulent flows. Typical applications are, for example, waves and turbulence within Earth’s atmosphere, shock-turbulence interactions in supersonic aircraft and rockets, interactions of high-speed fluid flows with elastic structures such as aircraft wings, and turbulence in chemically reacting, multiphase and supercritical fluids, such as fuel injection and combustion in rocket or car engines. In addition, Professor Hickel serves the European Research Community on Flow, Turbulence and Combustion (ERCOFTAC, of which SPHERIC is a Special Interest Group) as Chairman of the Scientific Programme Committee and TU Delft as Director of the Graduate School of Aerospace Engineering.
