FLOW INVESTIGATIONS ON THE HAMBURG TEST CASE MODEL IN THE WIND TUNNEL

Investigations of the so called "Hamburg Test Case", the wind tunnel model of an actual ship (the container carrier Ville de Mercure) were performed. The flow around one quarter of the model was measured in the wind tunnel with a three component laser doppler velocimeter. The measurements were taken in transverse planes. One measuring plane was located at the main frame, five at the stern an another in the far wake. The area covered by the grid of measuring points in each station extends outwards at leas to the extent of the main frame, except at the main frame station. The extent of the inner part is limited by the contour of the frame at the given X-station and by the symmetry plane of the flow. The evaluation of the measurements results in the presentation of the vector field of mean velocity and one component of the Reynolds stress tensor. Additionally the wall pressure at the stern is determined by pressure tabs on the hull. A visualization of the directional field of the wall shear stress distribution was performed in the same section. The pattern of the flow near to the plane of the propeller was visualised by a laser light sheet.
