Abstract
Present research is focused on combining High- Performance Computing (HPC) and Direct Numerical Simulation (DNS) of two-phase flows, to study the dy- namic behavior of rising bubble whit path instabilities with moderate/high Reynolds numbers ( Re > 1000 ). The Navier-Stokes equations are discretized us- ing the finite-volume approach; the pressure-velocity coupling is solved using a fractional-step projec- tion method, whereas the conservative level-set (LS) methodology is used for interface cap...
