This paper presents a computational study to better understand the underlying fluid
dynamics associated with various duct shapes and the resultant impact on both total vehicle …

Vortex induced vibrations (VIVs) may cause a large amount of damage to deep water risers.
Helical strakes are used as a mitigating measure to suppress these vibrations. The purpose …

Propulsor design methods utilize Computational Fluid Dynamics (CFD) to develop initial
propulsor configurations and predict the full-scale in-water performance of these optimal …

Integrated electric motor/propulsor technological development offers the potential to
increase usable volume for undersea vehicles by locating the electric motor in the duct. This …

Previous computational and experimental studies that have demonstrated a method to
generate vehicle maneuvering forces from a propulsor alone have been applied to a generic …

A method to generate vehicle maneuvering forces from a propulsor alone has been applied
to a generic undersea vehicle. Open and ducted post-swirl propulsors were configured with …
