Subscale Ship Airwake Studies Using Novel Vortex Flow Devices with Smoke, Laser-Vapor-Screen and Particle Image Velocimetry [PDF]
Ships produce vortices and air-wakes while either underway or stationary in a wind. These flow fields can be detrimental to the conduction of air operations in that they can adversely impact the air vehicles and flight crews.

A Conservative, Scalable, Space-Time Blade Element Rotor Model for Multi-Rotor Vehicles [PDF]
The development of a parallel blade-element rotor model and its implementation into an adaptive Cartesian method is described. The unsteady version of the rotor model applies a body force to all cells contained in the swept space-time volume at each ...

CFD Simulations of Unsteady LHA Ship Airwake in OpenFOAM
, 2018 Extensive research in the past two decades has shown that flow around the sharp edges of bluff bodies, such as the superstructure of a ship, can cause large scale shear-layer separations with increased turbulence, generating a highly unsteady flow in the airwake region.

Isolated rotor engagement and disengagement simulations in ship airwake
, 2016 During the engagement and disengagement phases of maritime helicopter operations, a transient aeroelastic phenomenon can occur, known as blade sailing. Characterised by large blade def lections, which have the potential to cause structural damage to the aircraft, blade sailing can limit the tactical flexibility of a helicopter operating in a maritime ...
