  • Combustion modelling in the Lattice Boltzmann Framework

    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, so 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.


    Research subject, work plan:

    Extending the LBM capabilities to combustion requires a profound rethinking of existing methods developed within the Navier-Stokes framework.

    The thermodynamic closure will first have to be extended to cope with multi-component ideal gas phase, including indeed the diffusive effects within (thermal and species diffusion). This, indeed, is a prerequisite to the second step, which will be to include the description of the kinetics responsible for combustion within the LBM framework. Serious fundamental work, as well as numerical modelling is indeed required.

     
    The postdoc will be part of one of the leading research groups on LBM in France, and will work under the direction of 

    • P. Boivin, combustion specialist   ( pierre.boivin[at]univ-amu.fr )
    • P. Sagaut, a world-renowned scientist on turbulence modelling and LBM   ( pierre.sagaut[at]univ-amu.fr )

  • Interfaces in reactive flows

    Research project and job description


    Summary:

    This project aims at developing a unified modelling method for flows that are both multiphase and reactive. Such complex flows are present in many applications. In cryogenic rocket engines, for instance, liquid oxygen is injected straight into the combustion chamber. The liquid jet is consequently strongly destabilised and atomised, before evaporating and burning with the surrounding hydrogen. Today, the processes corresponding to the liquid jet destabilization and to the combustion are tackled separately, without an appropriate coupling: no flow model has the capability of modelling both the multiphase and reactive aspects, whilst admittedly strongly coupled. 
    The objective is to develop a new model, allowing an accurate simultaneous representation of interfaces, phase transfer and combustion. For this, previous works [references available on request] will be extended as to encompass reactive flows. Validation will then be carried out on both multiphase and reactive academic test cases.

    Job description:
    The work will be carried at M2P2 (Pierre Boivin), in close collaboration with IUSTI (Jacques Massoni and Olivier Le Métayer). The two labs are within 5min walking and belong to the Fabri de Peiresc Federation.

  • Transition of propagation regime of forest fires

    Labex MEC “Mechanics And Complexity” Post-Doctoral position offer :

    Research project and job description


    Summary:

    This project aims at investigating the transition from plume dominated to wind driven fires. This transition has been characterized in the past based on two dimensional considerations. It is commonly associated with a stiff transition of the convective and radiative heat fluxes ahead of the fire front.

    Using multiphase three dimensional simulations on an equivalent static fire configuration, the objective of this work is to better characterize the transition and it's effect on the convective and radiative heat transfers. Finally, these simulations will be used to draw a map of the dimensionless configuration space {Byram ; CdLAI}. The simulations will be conducted using the solver ForestFireFOAM, an extension of FireFOAM developped at M2P2 to study forest fire propagation.

    Job description:
    The work will be carried at M2P2 with Aymeric Lamorlette, within the TONIC team.

    Essential skills:
    Strong background in scientific computing (C++, specific OpenFOAM object preferred), multiphase flows.
    Proficiency in scientific writing.

    Desired skills:
    FireFOAM, flow-vegetation interaction, combustion
