About BSC
 
The Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) is the leading supercomputing center in Spain. It houses MareNostrum, one of the most powerful supercomputers in Europe, and is a hosting member of the PRACE European distributed supercomputing infrastructure. The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress. BSC combines HPC service provision and R&D into both computer and computational science (life, earth and engineering sciences) under one roof, and currently has over 700 staff from 49 countries.

Context And Mission
 
The design of modern combustion systems needs to address challenges in aspects related to global efficiency, reduction of pollutant emissions, major flexibility of operation and reduction of thermo-acoustic instabilities. A strategy to reduce CO2 emissions and NOx is to operate lean, but problems of blow-off and instabilities might arise and mitigation strategies need to be developed. The use of lean premixed combustion technologies shifts the core strategy to reduce NOx, while keeping the flame stable at lean conditions. The design of the chamber comes with multiple requirements, more specifically concerning ignition, stability (including pressure oscillations), efficiency, and pollutant emissions, which makes its development a challenging task. Blending hydrogen with hydrocarbon-based fuels has been investigated as a potential strategy for reducing both GHG (CO2), due to lower fuel carbon content, and nitric oxides (NOx) emissions. These conditions will be investigated from the perspective of numerical simulations based on large-eddy simulation (LES) technique. This project is a nationally-funded project from the Spanish Minister in collaboration with CMT Motores Térmicos from Univertat Politècnica de València (UPV) and the Instituto de Investigación Aplicada a la Industria Aeronáutica (INAIA) from Universidad de Castilla La Mancha (UCLM).

The research team that the applicant will be involved is the Propulsion Technologies Group at CASE Department of BSC. The team is a multidisciplinary group with researchers from all disciplines and with strong background in Computational Fluid Dynamics (CFD). The team is involved in several EU and industrial projects related to this topic, where the successful activities and the publications on highly ranked scientific journals give the proved expertise.
