Inhaltsangabe oder Einleitung
In this paper flow over hexagonal patterns has been investigated. Investigations were performed in a subsonic Wind Tunnel. The Motivation behind these tests was to study the effects of the above mentioned hexagonal structures on the Flow of air and their contribution in reducing the Drag of the body. The Cylinders to be investigated were made by bending and welding patterned steel sheets once with facing the patters outwards and second the patterns facing inwards. The Orientation of these patterns towards the free stream of air was also changed during the Investigations and hence the investigations could be performed over five different configurations.
