A Computational Study of Unsteady Ship Airwake

Abstract : The superstructure, deck, and other features of large ships produce large separated regions in the airflow over the ship and a variety of vortex flows generated mainly by edges in the geometry. These features are of importance for aircraft operations on and around these ships. The ability to predict the airwake over a ship can aid in the development of aircraft operating envelopes and can be used to "diagnose" airwake structures that result in problematic or unusable landing spots. In addition, the ability to predict airwake could be used as a design tool to address air operations early in a ship design.
