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 500 staff from 44 countries.

Context And Mission

The main objective of the project is to develop a modelling strategy using CFD simulations for the prediction of soot in terms of chemical evolution and particle formation in conditions relevant to aero engine operation. The model developments are based on the use of detailed chemical kinetics for kerosene surrogates, and advanced combustion and spray models validated with reference experiments. It includes the development of efficient algorithms for the coupling of soot particles with gas phase dynamics allowing the use of large-scale applications with high computational efficiency. The candidate will be focused on the integration of soot models into a turbulent combustion model based on detailed chemistry and presume-shape PDF. The work departs from the validation of the turbulent combustion model at conditions representative of aero engine operation up to the simulation of the spray flame with soot generation in complex geometries. The project is defined in order to use high-fidelity numerical simulations to predict complex fluid phenomena in modern and new generation combustion systems. It takes place in the context of a scientific and industrial framework aiming to enhance the accuracy, flexibility, user decision and applicability of numerical tools for industrial design.

The research team that the applicant will be involved is the High-Performance Computational Mechanics Group at CASE Department of BSC. The team is a multidisciplinary group with more than 30 researchers from all disciplines and with strong background in Computational Fluid Dynamics (CFD). The team is involved in many EU and industrial projects related to this topic, where the successful activities and the publications on highly ranked scientific journals give the proved expertise.

The applicant will based at BSC, but will also interact with the project partners: Karlsruher Institute of Technology (Germany), Technischen Universität Berlin (Germany), Technische Universiteit Eindhoven (the Netherelands), CMT-Motores Térmicos (Spain), Technische Universität Darmstadt (Germany) and Universität Stuttgart (Germany).

Key Duties

The offered position is a Postdoctoral position for three years to investigate the formation of soot in spray flames.
