Ship Airwake Computational Modeling Method Verification [PDF]
, 2017 Computational Fluid Dynamics (CFD) simulations offer a feasible solution to resolving the behavior of ship airwake behavior in the interest of flight operations near a moving ship as opposed to large full scale experimental methods.

An Investigation of Frigate Ship Airwakes by RANS Modelling
, 2021 The operation of helicopters on-board ships has always been a very complex task owing to the presence of ship air wakes, high velocity gradients, widely varying turbulence length scales as well as the lesser area provided for helicopter operations.

Analysis of Ship Airwakes Using Modal Decomposition [PDF]
, 2021 The three-dimensional, unsteady, and turbulent airwake produced by a scaled model of a generic Navy ship (Simple Frigate Shape No. 2) was investigated in a low-speed wind tunnel.

An Integrated Time-Varying Airwake in a UH-60 Black Hawk Shipboard Landing Simulation [PDF]
, 2001 A non-stationary (time-varying) ship airwake model developed using computational fluid dynamics techniques was implemented in a blade-element model of a helicopter in order to represent the complex interactions between the rotorcraft and the turbulent ...

Experimental study of turbulent ship airwake [PDF]
© 2025 Ke ZhengWhen the atmospheric boundary layer at the air-sea interface blows over a ship, there is a highly turbulent airflow in its wake. For ships designed with a helicopter landing deck, understanding the turbulent ship airwake over the landing ...

The Effect of Ship Size on Airwake Aerodynamics and Maritime Helicopter Operations [PDF]
, 2015 This paper describes an investigation that has used piloted flight simulation to assess pilot workload while manoeuvring a helicopter over the landing decks of three different size, but similar, ships.

CFD Simulations of Unsteady LHA Ship Airwake in OpenFOAM [PDF]
, 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

Stochastic Simulation of Ship Airwake in Helicopter Shipboard Operation [PDF]
, 2022 For the development of a high-fidelity simulation environment for shipboard operations, modelling the unsteady aerodynamic loads caused by mutual interaction of the rotor wake and ship airwake is of great importance. In this paper, a stochastic modelling
