Project: Advanced Lattice-Boltzmann Modelling of Combustion Méthodes Avancées Lattice-Boltzmann En Combustion (MALBEC)  funded by the French National Research Agency (ANR)

Lattice Boltzmann (LB) solvers are becoming an ever more attractive alternative to traditional Navier-Stokes solvers. Reactive flow modeling in the LB framework, however, remain relatively marginal within the scientific community: most Lattice-Boltzmann schemes are limited to athermal flows.

Based our recent findings [1-8], Lattice-Boltzmann is an efficient [6] method for reactive flow simulations, including low Mach applications (plumes/fires) [3], thermo-diffusive instabilities [5], thermos-acoustic instabilities [2]. More recently, we have presented successful applications to detonations & thermos-acoustic instabilities on full-size burners [under review]. 

The team, now consisting of ~10 doctoral candidates and post-doctoral fellows is seeking a post-doctoral fellow, with experience in either:

- Turbulent combustion. The pdf structure of the LBM method allows for the development of new turbulent combustion models.

- Detonation or deflagration to detonation transition, for safety applications. 

The objective is to investigate these processes, taking advantage of the low dissipative character of both pressure and vortical modes of the NS system, when modelled via LBM. 

Note that the candidate is free to suggest alternative topics, matching his scientific interests. 

The candidate will have a PhD in computational fluid dynamics, with experience in the field of turbulent combustion (an experience with LBM is a plus). The numerical developments required will involve team-working skills to interact frequently with other postdocs/PhD students working on the same code, software engineers, associated industrials and supervisors. 

Send an application to: Pierre.Boivin@m2p2.fr including:

- A detailed CV 


- A cover letter 


Starting date: as soon as possible.

Contract duration: one year, renewable every year. 

Hydrogen appears to be a very promising energy vector and its production by fermentation, from the organic fraction of effluents, constitutes a way of recovering industrial waste. However, the development of this process within the water treatment sectors remains limited by two main bottlenecks: the control of the bacterial ecosystem and the conversion rate of the organic load, which is often insufficient to meet the environmental discharge requirements. In order to finalize the treatment and maximize the recovery of the effluent, the coupling of several biological processes

allowing the production of hydrogen and other recoverable molecules (VFA) is interesting in a circular economy approach.

In this context, this funded project "CAP-H2" aims to remove these limitations through a multi-scale interdisciplinary approach (from lab to demonstrator) in order to propose criteria for controlling these processes based on (i) the study of bacterial interactions and their impact on the productivity of the ecosystem and (ii) the optimization of the parameters of the coupled process.

The post-doctoral researcher selected will work within the Waste and Wastewater Treatment (TED) group of the M2P2 laboratory. The TED group conducts research in Process Engineering applied to the recovery of wastewater at the interface between the fundamental developments of academic research and industrial concerns for innovation in the development of processes. The laboratory has multi-scale experimental equipment allowing to carry out studies from the laboratory scale to the pilot scale. This project is carried out in collaboration with Athéna Recherche & Innovation, a company specialized in the production of hydrogen by biological means.

The successful candidate will be in charge of operating lab scale bioreactors for hydrogen or PHA production in the aim of determining the key parameters. Then the coupling of these reactor will be studied and optimized in terms of usual parameters (hydrodynamics, pH, HRT, etc). The determination of key process parameters is the innovative issue for an efficient carbon recovery of wastewater.

The candidate will ensure the tight interaction between academic and industrial partners. He/she will have to :

- Propose the experimental planning in agreement with his/her supervisor

- Conduct fermentations experiments at lab scale

- Analyze the results and communicate them in the expected format

PhD in bioprocess engineering

Knowledge of analysis techniques (chromatography, biochemical analysis, etc)

Strong communication and organizational skills

Good English skills are required

Applicants should send as soon as possible CV, summary of previous research and contact addresses of two references to:
