000014666 520__ $$2eng$$aWe present three-dimensional simulations of two types of very challenging jet flow configurations. The first consists of a liquid jet surrounded by a faster coaxial air flow and the second consists of a global rotational motion. Such liquid jet flow configurations require a high spatial resolution and are performed with a newly developed high performance parallel code, called BLUE, for the simulation of two- phase, multi-physics and multi-scale incompressible flows, tested on up to 131072 threads on the IBM BlueGene/Q machine with excellent scalability performance. The method for the treatment of the fluid interfaces uses a hybrid Front Tracking/Level Set technique that defines the interface both by a discontinuous density field as well as by a local triangular Lagrangian mesh. Coriolis forces are taken into account and solved via an exact time-integration method that ensures numerical accuracy and stability.
