Hello. I am Lucien and welcome to my website. I have finished my Ph.D. thesis at the end of 2019, and I continue my research as a postdoctoral researcher in the LMFA laboratory for the upcoming year. My research interests include fluid dynamics, lattice Boltzmann method, multi-species diffusion, kinetic theory, and physical oceanography.
Besides my research, I can’t decide between the seaside and the mountainside enjoying windsurfing, sailing, as well as hiking, and mountain biking.

In nature, chemical compounds commonly mix each other. One of the elemental material in fluid mechanics, air, is predominantly composed …
The lattice Boltzmann method (LBM) is a specific discrete formulation of the Boltzmann equation. Since its first premises, thirty years ago, this method has gained some popularity and is now applied to almost all standard problems encountered in fluid mechanics including multi-component flows.
A lattice Boltzmann method for miscible gases is presented. In this model, the standard lattice Boltzmann method is employed for each species composing the mixture. Diffusion interaction among species is taken into account by means of a force derived from kinetic theory of gases. Transport coefficients expressions are recovered from the kinetic theory. Species with dissimilar molar masses are simulated by also introducing a force. Finally, mixing dynamics is recovered as shown in different applications: an equimolar counterdiffusion case, Loschmidt’s tube experiment, and an opposed jets flow simulation. Since collision is not altered, the present method can easily be introduced in any other lattice Boltzmann algorithms.
In the first part of the presentation, we introduce a lattice Boltzmann model for miscible gases. In this model, the standard lattice …
