Presentation

LFD-FLU is an Inria associate team between the Fluminance Inria group and the LFD laboratory of the Buenos Aires university. The LFD-FLU team, which gathers researchers from both groups, aims at exploring issues related to the modelling of the small-scale flow components through the incorporation of random fields, figuring uncertainties on the flow dynamics. This strategy allows us modelling partially known boundary conditions or missing dissipation contributions associated to unresolved scales or truncated modes. This strategy will be coupled with a continuation of our common past efforts on the study of empirical basis for the flow representation.

Principal investigators

Etienne Mémin, Leader of the Fluminance research group jointly affiliated to Inria, Irstea and the IRMAR laboratory

Guillermo Artana, Head of the LFD laboratory of the Buenos Aires University
