Workshop on Multiscale and directional approach to single-phase and two-phase flows
École Centrale de Lyon
- to gather experts from the turbulence field after this hard and long period of Covid 19 lockdown. Everyone will be welcome to present a talk on what “keeps his heart beating so fast” around the multiscale physics in one-and-two phase turbulence.
- to extend an interface between two GDRs, one is the GDR 2865 on the phenomenology of turbulence, and another is the GDR 2042 on the transfer and interfaces. Two coordinators of those GDRs will present a short introduction to their GDR.
- to take part in the discussion on the new focus of interest in the fluid mechanics “turbulence of respiratory strays” (TORS) with eventual points on high-speed production of droplets under accelerating/decelerating air-blast, on turbulent dynamics and clustering of droplets in air jets (with and without buoyancy), on droplets evaporation under highly turbulent conditions,on new ways of the room ventilation, àn the improved methods in pathogen droplets removal, etc.
- Mikhael Gorokhovski (LMFA, Ecole Centrale de Lyon, France)
- Carlo Massimo Casciola (La Sapienza Università, Rome, Italy)
This is a join ERCOFTAC event with SIG35, SIG39, SIG50 and PC Henri Bénard
Provisional program, November, the 12th and 13th
