Für die Untersuchung turbulenter Grenzschichten existiert bisher kein Messsystem, das in der Lage ist, die Wandschubspannungsverteilung quantitativ, flächig und zeitlich hoch aufgelöst zu bestimmen. Da der Micro-Pillar-Shear-Stress-Sensor MPS³ die Möglichkeit bietet, dieses Ziel zu erreichen, w...
Wall-shear stress results from the relative motion of a fluid over a body surface as a consequence of the no-slip condition of the fluid in the vicinity of the wall. To determine the two-dimensional wall-shear stress is of utter importance in theoretical and applied turbulence research. However, des...
For wall-bounded turbulent flows, knowledge of the mean and the fluctuating components of the wall-shear stress is of vital importance for the investigation of near-wall flow structures, which are responsible for the turbulent energy and momentum transfer. In this study, the wall-shear stress dis...
In this work, we employed micromechanical techniques on directionally solidified NiAl-Cr prepared at different solidification speeds, to understand the effect of processing conditions and the role of individual phases and interfaces on the deformation behaviour. The observations from the different t...
This Special Issue presents selected papers from the 8th Symposium on Micro–Nano Science and Technology on Micromachines, 31 October–2 November, 2017, in Hiroshima, Japan.
