Description
The Front-Tracking method has been implemented in TrioCFD and improved over the last
decade. It has been widely used on large parallel architectures to study incompressible two-
phase flows. The permanent increase in computing capabilities allows to perform simulations
of fully turbulent bubbly flows in relatively small periodic domains. This talk will be organized
in two parts. The numerical method used to perform Front-Tracking simulations will be
presented. The code is capable to deal with phase change and specific Ghost-Fluid Methods
have been implemented to guarantee a great accuracy of the solution, even in the presence
of large jumps and phase change.
Then, recent calculations on adiabatic two-phase turbulent bubbly flows will be presented.
Averaged results are analyzed in great details in order to better understand the dominant
processes in the exchange mechanisms at the interface and in the modulation of turbulence
by the vapor inclusions and their wakes. Preliminary results and suggestions for the two-fluid
model will conclude the presentation.
