Tubulence

The team’s research centers around the applications of fluid mechanics and problems associated with environmentally-related turbulence:

- variable mass volume jets: risks associated with stocking hydrogen under high pressure for the general public to use combustible batteries

- turbulent boundary layers developing on environments: modeling aerosol uptake on green space and urban areas

- liquid two-phase jets and their fragmentation: spraying pesticides and sprinkler irrigation

- aerodynamics and aeroacoustics: automobile industry and passenger comfort

- sedimentary erosion: river barrier preservation

Most of these activities are conducted using financing obtained from a combination of ANR programs, the Ministry of Ecology, or the Institut Carnot STAR.
