The understanding of turbulent two-phase flows with droplets or bubbles is important in many natural and industrial processes, e.g., rain formation, breaking ocean waves, spray cooling, and spray atomization in combustors. In these flows, the turbulence is altered by the droplets/bubbles feedback on the surrounding fluid and, indirectly, by their mutual interaction. Indeed, droplets and bubbles can deform, develop internal circulation, break up and coalesce, thus, complex mechanisms are expected to be active. We present numerical simulations of the flow of two incompressible and immiscible fluids in a homogeneous shear turbulent flow.
