Multiphase flows play an important role in the performance of virtually all surface and undersea systems. From a computational modelling perspective, the complexities of large density ratio, non-equilibrium dynamics, discrete interfaces, multiphase compressibility, mass transfer, multiple gas species, and other physics, require the use of high pedigree numerics, validated physical models and large-scale parallel simulation. In this talk we focus on flows where dynamic discrete interfaces exist/arise that interact importantly with the motion of the vehicle. In this context, our group has studied developed cavitation and free-surface dynamics for a number of years and consider six-degree-of-freedom flow-body interactions. In this talk we explore the CFD technologies we have developed and applied for surface craft and wave energy harvesting devices, developed cavitation on propellers and maneuvering super-cavitating systems. Underlying numerical elements including free-surface capturing discretization, preconditioning, mass transfer, six-degree-of-freedom dynamics coupling, and overset and adaptive meshing are discussed as important elements in our modelling. A number of examples are provided that illustrate the state-of-the-technology in this CFD design environment.
