Abstract

This paper describes an experimental study in which a 1:200 scale model of the Queen Elizabeth Class aircraft carrier was submerged in a water channel, and Acoustic Doppler Velocimetry was used to measure the unsteady flow over the ship’s superstructure. The study was conducted to provide experimental data to compare with a CFD prediction of the air flow over the full-scale, 280m long, ship. The paper describes the experimental technique and discusses the scaling issues between a 1:200 small-scale model in a water channel and the full-scale ship. The CFD was carried out using Delayed Detached Eddy Simulation to provide 30 seconds of the unsteady flow over and astern of the ship. The same CFD methodology was also applied to the small-scale experiment to provide further information on the scaling issues. While the detail of the CFD is not the main subject of the paper, a brief description is given, and comparisons are made between the experimental measurements and the CFD solutions.
