Two-phase flow in gas turbine compressors occurs, for example, at heavy rain flight condition or high-fogging stationary turbines. The liquid dynamic processes are independent of the application. An overview on and their approach literature is given. focus this study lies experimental investigation trailing edge disintegration. In experiments, shadowgraphy used to observe disintegration a singl...

We demonstrate optical trapping of rare earth-doped NaYF 4 :Er/Yb nanorods high aspect ratio (length 1.47 μ m and diameter 140 nm) using a quasi Bessel beam (QBB) generated by positive axicon fiber tips. Propulsion or the is demonstrated either single dual nano-tip geometries. The force exerted on trapped nanorods, their velocities, positions have been analyzed. determine trap stiffness for nan...

Temperature plays an important role in spin-torque switching of magnetic tunnel junctions, causing magnetization fluctuations that decrease the voltage but also introduce errors. Here we present a systematic study temperature dependence spin-torque-switching probability state-of-the-art perpendicular-magnetic-tunnel-junction nanopillars (40--60 nm diameter) from room down to 4 K, sampling up mi...
