A Stochastic Model of Unsteady Ship Airwake Disturbances on Rotorcraft
, 2009 Shipboard operations present challenging piloting tasks due to unsteady ship motion and airwake behind the ship. Researchers have been working to accurately simulate the ship airwake through computational fluid dynamics (CFD).

The effect of ship shape and anemometer location on wind speed measurements obtained from ships
, 2005 Wind speed measurements obtained from ship-mounted anemometers are biased by the distortion of the airflow around the ship's hull and superstructure. These wind speed measurements are used both in numerical weather prediction and in climate studies and ...

Time-accurate computational fluid dynamics modeling of the LHA ship airwake
, 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
