**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, was a founding and hosting member of the former European HPC infrastructure PRACE (Partnership for Advanced Computing in Europe), and is now hosting entity for EuroHPC JU, the Joint Undertaking that leads large-scale investments and HPC provision in Europe. 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 1000 staff from 60 countries.

**Context And Mission**

The objective of this project is to develop a numerical methodology for compressible flow simulations in LES. The methodology, to be integrated in the in-house solver Alya, will be coupled to tabulated chemistry using the Flamelet Progress Variable (FPV) approach for modelling combustion. The solver will be validated with canonical problems relevant to supersonic combustion, and will be applied to high-speed reactive mixing layers of hydrogen and air, which are relevant to scramjet configurations.

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 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.

**Key Duties**
- Collaborate with the different partners of the projects to carry our collaborative research.
- Contribute to scientific publications and reporting to different National and EU projects the researcher will be involved in.
- Focus will be on the reactive flow equations to solve combustion problems, such as hydrogen combustion.
- The solver will be integrated into the in-house, multiphysics code Alya. Once developed, it will be used to study both canonical problems, such as high-speed shear layers, and industrial configurations, such as supersonic combustion in scramjets.

**Requirements**:

- Education
- PhD in Chemistry, Physics, Mechanical Engineering, or Aerospace with background in fluid mechanics and thermal systems.
- MsC or Degree in Chemistry, Physics, Mechanical Engineering, or Aerospace with background in fluid mechanics and thermal systems.
- Essential Knowledge and Professional Experience
- Knowledge of fluid mechanics and thermodynamics are expected.
- A solid background in data-driven methods and Artificial Intelligence will be positively evaluated.
- Additional Knowledge and Professional Experience
- General knowledge on computer science and programming languages such as Fortran, Python, C, and C++ will be considered an asset.
- Basic knowledge of HPC will be appreciated.
- Fluency in English is essential, Spanish is a plus.
- Competences
- Strong analytical skills.
- Ability to work independently and within a team. Good communication and team-work skills to work in a multidisciplinary team.**Conditions**
- The position will be located at BSC within the CASE Department
- We offer a full-time contract (37.5h/week), a good working environment, a highly stimulating environment with state-of-the-art infrastructure, flexible working hours, extensive training plan, restaurant tickets, private health insurance, support to the relocation procedures
- Duration: Open-ended contract due to technical and scientific activities linked to the project and budget duration
- Holidays: 23 paid vacation days plus 24th and 31st of December per our collective agreement
- Starting date: 01/02/2025

**Applications procedure and process**
- A full CV in English including contact details
- A Cover Letter with a statement of interest in English, including two contacts for further references - Applications without this document will not be considered
