Abstract: We present a high performance computing framework for multiphase, turbulent flows on structured grids. The computational methods are validated on a number of benchmark problems such as the Taylor-Green vortex that are extended by the inclusion of bubbles in the flow field. We examine the effect of bubbles on the turbulent kinetic energy dissipation rate and provide extensive data for bubble trajectories and velocities that may assist the development of engineering models. The implementation of the present solver on massively parallel, GPU enhanced architectures allows for large scale and high throughput simulations of multiphase flows.
