Keywords

hydrodynamic instabilities, integrated computation and experimental fluid dynamics, three-dimensional unsteady separation, Yaw motion and dynamic maneuvers

Background

Physics-based simulation capability for naval vehicle maneuvering in normal and extreme operations is of timely importance due to expanded design specifications and standardization of maritime regulations. RTG will enable improved high-fidelity simulation capabilities thereby providing innovative design opportunities to meet challenges of 21st century naval vehicles.

Objectives

First objective is to provide accurate data from model experiments with capturing turbulence flow features by mean of specific instrumentation like tomographic particle image velocimetry. Second objective is to assess the validity of simulation tools in dynamic manoeuvers specifically concerning vortex propagation.

Topics

Yaw motion and dynamic maneuvers, three-dimensional unsteady separation, hydrodynamic instabilities, integrated computation and experimental fluid dynamics.
