A Restricted Nonlinear (RNL) framework for navy vessel boundary layers: Exploiting reduced order modeling to inform new drag reduction strategies

Abstract

This project develops the core theory and simulation tools to extend restricted nonlinear models tocharacterize the effects of different surface characteristics on skin-friction drag. The resulting suiteof reduced-order model based tools will enable efficient testing of flow manipulation strategiesbased on changes to naval vessel surfaces. The results can be used to guide the focus of exper"imentalor fully resolved numerical investigations of these hydrodynamic processes that are criticalto the Navy and, most important""ly, reduce the number of these far more expensive studies.
