Organizers: Alfredo Soldati, Paolo di Marco, Iztok Zun, Gian Piero Celata (Honorary Chair) Direct Numerical Simulation of turbulent convection, courtesy of F. Zonta The European Two−Phase Flow Group was established on October 4, 1963, at the Royal Institute of Technology in Stockholm [...] All subjects related to gas−liquid as well as fluid−solid flows can be discussed at the Group Meetings. Boiling, flashing and condensation, dispersed flows (bubbly, droplet and particle laden flows), turbulence interactions, flow pattern regimes, singularities and choked flows, reacting flows, environmental and biological flows, experiments, theory and simulations.
