PRACEdays17 Best Poster Award
For the first time the PRACE Best Student Poster Award was presented. Martin Vögele (Max Planck Institute of Biophysics) received the prize for his poster entitled “ Finite size effects on the dynamics in simulations of lipid membranes“.
The PRACE Best Poster Award was awarded to Felipe Nathan Oliveira (Barcelona Supercomputing Center) for his poster entitled “Nonlinear electromagnetic stabilization of ITG microturbulence by ICRF-driven fast ions in ASDEX Upgrade”.
Nonlinear electromagnetic stabilization of ITG microturbulence by ICRF-driven fast ions in ASDEX Upgrade
Tokamaks are devices used to confine a fusion fuel mixture heated to high temperatures in the range of hundreds of millions of degrees, arriving in a state of matter called plasma. Several auxiliary systems are used for this purpose. They include Neutral Beam Injection (NBI) and electromagnetic waves. The largest tokamak up-to-date, aiming to achieve self-sustained nuclear fusion, is the International Thermonuclear Experimental Reactor (ITER) shown in figure 1. It is presently under construction in Cadarache, France.
DNS of Gravity-Driven Bubbly Flows
Present research is focused in combining High Performance Computing (HPC) and Direct Numerical Simulation (DNS) of gas-liquid multiphase flows, in order to study isothermal gravity-driven and thermocapillary-driven (g = 0) bubbly flows in a vertical channel. The Navier-Stokes equations and energy equation are discretized by means of the finite-volume approach, the pressure-velocity coupling is solved using a fractional-step projection method, whereas the conservative level-set (LS) methodology is used for interface capturing, thus, mass conservation issue that is known to affect standard LS methods, is circumvented. On the other hand, one of the disadvantages of interface capturing methods is the numerical and potentially unphysical coalescence of the fluid-interfaces. In this work, a novel multiple marker level-set methodology is used in order to avoid the numerical coalescence of the bubbles, indeed, long time simulations of bubbly flows including bubble collisions can be simulated.
