Multiphase Turbulence Modeling for Computational Ship Hydrodynamics

Abstract

Highly mixed turbulent bubbly flows in the near and far field of a ship have become a critical consideration in the design of the modern Naval surface ship. While the prediction (and detection) of the bubbly cloud is most relevant for the far-field wake, it is the near-field ship geometry and motions that provide the source of this bubble field. While there have been major advances in both the prediction of the near-field ship flow and the evolution of the far-field bubbly wake, physics-based modeling and efficacious design closure bridging these two regions remain a significant challenge. This strategically focused effort aims to bridge this gap in Computational Ship Hydrodynamics (CSH) capability.
