HPC4E contributes to defining an HPC Roadmap for Energy Industry

The HPC4E project organised the HPC Roadmap for Energy Industry on Wednesday, 1 February hosted by INRIA Sophia Antipolis (France). The agenda of the event included a talk by Paul Gibbon, EoCoE coordinator, who summarized the main achivements of EoCoE and its future plans, Jeroen Van Oijen, Technische Universiteit Eindhoven, Arnau Folch, Barcelona Supercomputing Center (BSC), Henri Calandra, TOTAL and both HPC4E coordinators José María Cela (BSC) and Alvaro Coutinho (COPPE).

Professor Jeroen Van Oijen presented a lecture, about “Combustion of bio-fuels”. This presentation gave an overview of the potentials of the use of biomass for energy and power highlighting the current technologies and the challenges associated to the modelling of these systems. Results were presented in terms of the state-of-the-art of the use of DNS and LES for laboratory flames and practical combustion systems.

The modelling of combustion systems and in particular, those using alternative fuels are still far from being currently possible with the computational resources available as the chemistry is stiff and highly non-linear requiring extremely large computations.

Detailed chemistry simulations for both DNS and LES are still not possible, and chemistry reduction techniques (reduced kinetics, FPI, FGM) need to be considered in order to model these systems. Using these techniques, DNS and LES simulations become possible and the limitations come only from the fluid mechanics part instead of the chemistry part.

On the other hand, environmental simulations BSC group manager, Arnau Folch, presented a session titled ‘Wind Energy and HPC at Barcelona Supercomputing Center (BSC)’ where he explained the research lines related to wind energy at the Computer Applications in Science and Engineering (CASE) Department. These include a series of RANS models for the Atmospheric Boundary Layer (ABL) and wind farm simulations in complex terrains, LES models implemented for wind energy related simulations, and a suit of mesh generation software tools for winds on complex terrains and wind farms. Detailed LES wind farm simulations covering all the different spatial scales require of Exascale technology.

The second session of the workshop included a talk by Henri Calandra from TOTAL. Geophysical exploration is an important driver for HPC since the last couple of decades. This can be observed in Top500 list, where most of the biggest industrial HPC systems in the world belong to this area. HPC4E workshop clearly stated that this is not a temporary trend. The exascale technology is a necessity for the field as every day the exploration of energy resources become more and more challenging. A challenge that can only be contested with HPC.
