high performance computations of multiphase flows

We will discuss the current state of the art of very large multiphase flow simulations for flows involving very large ranges of scales, such as those involving liquid jet high speed atomisation producing very small droplets, the ladle flows in metallurgy at very large Schmidt numbers, and the boiling flows at large Jakob numbers. It is likely that high performance octree and VOF methods will not by sufficient to reach the exascale and that other techniques, such as time parallelisation, will be needed.
