Large scale fully resolved bubbly flow simulations is the emerging capability which is giving promising results in understanding the multiphase flow behavour. The presented video demonstrates the large scale simulations (more than two billion elements) for four different geometries: parallel plate channel; circular pipe; a single subchannel geometry from a nuclear reactor core and a 2x2 subchannel geometry with fully resolved spacer grids and mixing vanes from a pressurized water reactor core. We also show mean velocity, turbulent kinetic energy and void fraction distributions collected from the presented simulations.
