ERCOFTAC Workshop at École Centrale de Lyon


Mercredi 23 et Jeudi 24 janvier 2019 en Amphi 1 (bâtiment W1, ECL)


The aim of the ASTROFLU IV workshop is once again to gather the fluid mechanics specialists from the physics, engineering, astrophysics, and mathematics communities in order to exchange ideas and collaborate on our common interests.
ASTROFLU IV will mark a new orientation compared to the previous events, with :
• Emphasis on plasmas physics, both in astrophysics / heliophysics and in engineering, as the studies for controlled nuclear fusion by electromagnetic confinment (ITER).
• To explore the analogy between radiation of acoustic waves and the very recent theory of gravitational wave turbulence, from aeroacoustics in Engineering to cosmology.
