Postdoctoral Position in Numerical simulations of soot formation in aero engine

Research project
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.

Research group description
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).

Job position description 
The offered position is a Postdoctoral position for three years to investigate
the formation of soot in spray flames. The expected work can be divided into
three main stages:
- Validation of the Conditional Moment Closure for LES using detailed and
reduced chemistry for kerosene.
- Integration of a Lagrangian atomization model.
- Coupling with existing soot models.

The work conducted in the project will be performed with the parallel
multiphysics code Alya, which is an inhouse finite-element solver developed at
BSC. The applicant is expected to get familiar with the code running
benchmarking cases, and developing physical models that will be integrated in
the multiphysics platform of Alya. The candidate should hold a PhD in Aerospace,
Aeronautics or Mechanical Engineering degree with concentration on turbulence
and combustion. General knowledge on fluid mechanics, LES, numerical methods,
soot, combustion chemistry are expected. Computational skills and parallel
programming for HPC are not necessary, but will be considered an asset. Some
familiarity with the Conditional Moment Closure will be a plus.

Application should be submitted via the BSC website:
