Investigation of Flow over bluff bodies with patterned surface using Laser-Doppler Anemometry

Research Paper (postgraduate) from the year 2012 in the subject Engineering - Mechanical Engineering, grade: 1,0, Brandenburg Technical University Cottbus, language: English, abstract: 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.

An expert in Experimental Fluid dynamics, I did my Bachelors and Masters in Mechanical Engineering from Universities of Mannheim and Germany. During my studies i got the opportunity to gain initial industrial experience at EADS (European Air Defence and Space) and ELOPAK. I completed my PhD from the Technical University of Cottbus, Germany. My doctoral work focused on investigating drag reduction using structured surfaces in a wind tunnel. After submitting the Dissertation i worked for Siemens in Berlin as Test Engineer. Recieved research Grant of 0.1 million Euros from DAAD. Currently developing micro gas turbines at institute of Aeroengines in BTU Cottbus.
