  • Postdoctoral position "Instabilities of stratified shear flows"


    Description of the position
    Our project aims to strengthen the links that exist between the Technical University of Brandenburg (BTU) in Cottbus in Germany and Aix-Marseille University, more particularly between the IRPHE and M2P2 laboratories and the department of aerodynamics and fluid mechanics of Cottbus.
    Co-workers 

    • P. Le Gal, IRPHE, Marseille, France
    • B. Favier, IRPHE, Marseille, France
    • S. Viazzo, M2P2, Marseille, France
    • U. Harlander, BTU Cottbus, Germany

    Description of the work
    Therefore, we propose to hire a post-doctoral collaborator in order to continue our research by numerical simulations on the nonlinear dynamics of instabilities of sheared stratified flows. Two actions will be carried out simultaneously: the first on the stratified Poiseuille flow [1]. The research will be supervised by B. Favier who has already carried out the first flow simulations. Alongside this work in Marseille, missions will take place in Germany in order to share the numerical and theoretical results and to proceed with the preparations for possible modifications of the experimental set-up as well as the performance of some preliminary experiments.
    The second action of this first year of work will be supervised by S. Viazzo at M2P2. This will involve performing numerical simulations of baroclinic instability [2] with vertical density gradient [3]. Missions will also take place in Cottbus in order to share the experimental results previously acquired.

    We plan for 2022/2023 to continue this research with a second year of post-doctoral internship funded by BTU on its Flagship program:
    https://www.b-tu.de/en/researchschool/funding-opportunities/flagship-fellowship

    The research will be devoted mainly to carrying out experiments. As for the first Marseillaise year, the two types of instabilities will be studied: the Poiseuille flow will be the subject of measurement campaigns by PIV in nonlinear regimes not reached so far. In the second part of the project, the post-doctoral student will devote part of his or her time to the study of the barostrat instability [3]. In particular, he or she will compare the numerical results obtained by the simulations made at M2P2 and the measurements made at Cottbus recently or during new measurement campaigns that he or she will carry out under conditions which will have been specified by the results of the numerical calculations. U. Harlander will supervise this experimental research.

    • A 3-month period at Aix Marseille University in France (September 1 to November 30).
    • A 9-month period at the University of Alberta in Canada (December 1, 2021 to August 31, 2022).

    Description of the work
    The laboratory M2P2 is currently involved in a collaborative project, entitled FASTECO2, funded by the French public program “PIA”, programme d’investissements d’avenir. One of the objectives of the project FASTECO2 is to implement an innovative process of sterilization using supercritical CO2 (sc CO2) particularly adapted to polymeric implantable medical devices. The project consortium is composed of two universities (University of Lille and AMU) and three private companies (LATTICE MEDICAL, COUSIN BIOTECH, GREENCHEM).
    Supercritical CO2 sterilization is an alternative to thermal and non-thermal sterilization treatments that have limitations. Supercritical sterilization has a great potential for the inactivation of dry powders in different fields of applications: food (spices, herbs, aromatics, etc.), drugs as well as cosmetics. A huge market is now emerging for the sterilization of medical devices since the conventional methods (ethylene oxide treatment and ionizing radiation) cannot be used for all types of materials. Moreover, major progress has been achieved over the last decade in this field. Advances in tissue engineering brought new types of scaffolds and implantable medical devices, which require more than ever an efficient, non-toxic and low temperature sterilization method.
    A large part of the experimental work of the laboratory M2P2 will be dedicated to a parametric study of sterilization carried out using a panel of strains.
    In parallel to the process development, the Laboratory M2P2 aims to perform a more fundamental study, in collaboration with the University of Alberta, so as to go further in the understanding of sc CO2 inactivation mechanisms. The different biocidal effects of sc CO2 have already been described in the literature but there is a real need to sharpen the knowledge about sc CO2 effects on microorganisms, particularly bacterial endospores. The inactivation efficiency is linked to the different operating parameters and conditions such as the temperature, pressure, and treatment duration. In the literature, temperature is described to be the key-parameter but increasing the pressure and the process duration allows also to increase significantly the bioburden lowering. Since one of the effects of sc CO2 is the acidification of the extra and/or intracellular media, the addition of an acidic agent is also a solution for enhancing the inactivation effect.
    The objective of the postdoctoral work will be to go further in the understanding of sc CO2 inactivation mechanisms carrying out an experimental work so as to discriminate among the different effects.

  • Novel and efficient algorithms for immersed moving structures in realistic industrial conditions in aeronautics using lattice Boltzmann method

    Domain : computational fluid dynamics, aeronautics, fluid structure interactions

    Project : Advanced Lattice-Boltzmann Understandings for Multiphysics Simulations (ALBUMS) funded by Airbus, Safran, Renault and the French National Research Agency (ANR)

    Description
    Although the motion of immersed solids in rotation is relatively well captured by available numerical codes based on Lattice Boltzmann Method (LBM), the reliable simulation of immersed structures approaching each other, or immersed structures in motion in the vicinity of a fixed wall, still remain an open issue for industrial applications. The objective of the work is to develop novel and efficient algorithms to tackle these configurations involving complex fluid/solid interfaces with contact, and mesh adaption in the LBM framework, including rigid and deformable objects.

    Expected profile of the candidate
    The candidate will have a PhD in computational fluid dynamics. The numerical developments required in the PhD will involve team-working skills to interact frequently with other students working on the same numerical code, software engineers, associated industrials and supervisors.

    How to apply
    Send an application to: Julien.Favier@m2p2.fr and Pierre.Sagaut@univ-amu.fr including:
    - A detailed CV
    - A cover letter

    Starting date: From April 2021, or earlier
    Deadline to apply: 10/05/2021
  • 2 Postdocs on LBM : 1 postdoc on "multicomponent compressible flows" & 1 postdoc on "combustion"

    Topic : Lattice Boltzmann Lattice-Boltzmann methods

    Background, Context :
    The industry relies increasingly on numerical simulation for designing, improving, and even validating new combustion devices (engine, burner, furnace, etc.). Today, numerical combustion modelling relies almost exclusively on numerical codes solving the Navier-Stokes equations. 
    The Lattice Boltzmann solvers are very different from these codes, intending to solve a discrete variant of the Boltzmann equation. This type of flow solver is progressing rapidly, however, in turbulent flows configurations. The results obtained with Lattice Boltzmann methods (LBM) have shown to be excellent for aerodynamic applications, motivating intensive development of new methods.
    Lattice Boltzmann methods applied to industrial applications are recent, however, and few models are able to deal with multiphase flows, and almost none with reactive (combusting) flows. 
    The development of combustion modelling within the LBM framework is the topic of this study, following our recent works. 

    Research subject, work plan :
    Extending the LBM capabilities to combustion requires a profound rethinking of existing methods developed within the Navier-Stokes framework. 
    The team has recently made important steps in proving the LBM ability to tackle such flows, at a cost significantly reduced compared to classical results, on relatively simple configurations.

    Two positions are available (all on LBM): 

    - 1 postdoc on multicomponent compressible flows

    - 1 postdoc on combustion


    Contracts : 1 year for postdoc, renewable for a 2nd year / Salaries depending on experience, according to Aix-Marseille University standards. 

    Essential skills : Strong background in scientific computing (c++ preferred), compressible flows, reactive and/or multiphase flows. English.
    Desired skills : LBM, HPC, French.

    Application : Email CV, cover letter to pierre.boivin@univ-amu.fr.

    Intended Start date: In 2021, negotiable depending on profile.
