5th March 2021; 02:00 PM (Paris time, GMT+1)

3rd Zoom Meeting: Zoom: link; ID: 926 5516 0136; Code: 432785

On 5th March 2021 at 02:00 PM (Paris time), the ERCOFTAC Pilot Center Henri Bénard will organize its third zoom-meeting on “COVID19 Flows: Fundamentals and Practical Recommendations”.

The main points in two invited lectures include the characterization of respiratory sprays (formation, ejection, turbulent fluid and thermal dynamics), and the impact of different masks on the flow physics. We are pleased to be joined by Professor Detlef Lohse (University of Twente) and Professor Christian Kähler (Bundeswehr University Munich). The program, abstracts and zoom link are in attached.
