The modeling of multiphase flow with the hybrid multiphase lattice Boltzmann model1 is highly efficient; however, it usually suffers from numerical instability at large density ratios, Weber numbers, and Reynolds numbers. Our recent model2 employs a consistent pressure scheme, high bulk viscosity, and a relatively thick interface width to stabilize the computation, but this approach simultaneously decreases accuracy. This internship will integrate advanced algorithms to enhance the numerical stability and accuracy of the hybrid multiphase lattice Boltzmann model.

THE CANDIDATE

You are a final-year student in an Ecole d’Ingénieur or enrolled in a Master 2 program, specializing in fluid mechanics, numerical simulation, or applied mathematics. Basic knowledge of multiphase flows and the finite volume method is required. Experience or a strong interest in programming (Fortran or C++) is an asset, and knowledge of parallel computing paradigms is welcome. Good English communication skills, both spoken and written, are required.

Your CV, cover letter, and grades for the last two years are to be sent to:
