dc.description.abstract-translatedThe size of velocity-vector fields obtained from numerical solutions of the Navier-Stokes equations for three-dimensional, time varying and turbulent flows is extremely large. Stereographic systems can intuitively depict the small depth movements and relations between fluid particles that standard perspective projections fail to. As expensive high-end-stereographic systems aim at one user one computer and are therefore not suitable for demonstration purposes in lectures, the anaglyph method is applied for visualizing turbulence in a stereographic movie to a large number of people. A solution to overcome the effect of ghosting, which has been a major drawback in the use of anaglyphs, is introduced. A twofold central projection was found to be superior to standard on-axis projections in graphics hardware allowing an easy representation of objects in front of and behind the projection plane and thus enhancing the stereoscopic effect. The visualization system deals with the small fluctuations of the velocity about its mean values (i.e. the so called rms values) to depict real turbulence in a pipe flow at reynolds number Re≈7000.en
