Submerged wakes in littoral regions

Ultra-large-scale computations with minimal empiricism are being performed under this challenge project to study turbulent flow behind submerged vehicles operating in coastal environments. Large-scale challenge resources are enabling the first-ever simulations of submerged propelled vehicles undergoing complex maneuvers induced by moving control surfaces. Simulations of the flowfield itself, including the effects of stratification and trailing vortices are also being conducted. Together, these simulations will supply valuable knowledge of maneuvering characteristics and their effect on the flowfield including the complex characteristics of the litorals: stratification, shear, shallow water, and wave motion.
