Experimental investigation of Taylor-Couette-Poiseuille flow at low Taylor and Reynolds numbers.

open access: yesPLoS ONE, 2019
Flow patterns of a Taylor-Couette-Poiseuille flow were studied at low axial Reynolds and rotational Taylor numbers (Re ≤ 10.5, Ta ≤ 319). The radius ratio of the inner and outer cylinders was 0.804 and the ratio of the length of the annulus to the gap ...

Investigation of crack propagation patterns on the borehole wall during single-borehole hydraulic fracturing under different in-situ stress ratios

open access: yesScientific Reports
To study the initiation, propagation, and mechanical behaviour characteristics of fractures on the wall of a single hole during hydraulic fracturing for in-situ stress measurement, and to improve the accuracy of stress direction discrimination in ...

Diverging Relaxation Times of Domain Wall Motion Indicating Glassy Dynamics in Ferroelastics [PDF]

open access: yesMaterials Research, 2018
Single crystals of PbZrO3 and LaAlO3 have been studied by Dynamic Mechanical Analysis measurements in the low frequency range f = 0.02-50 Hz. The complex Young's modulus exhibits a quite rich behavior and depends strongly on the direction of the applied ...

Shifted periodic boundary conditions for simulations of wall-bounded turbulent flows

open access: yes, 2016
In wall-bounded turbulent flow simulations, periodic boundary conditions combined with insufficiently long domains lead to persistent spanwise locking of large-scale turbulent structures.

Schematic view on the precentral gyrus at the medial wall.

open access: yes, 2013
The standard current direction is in lateral direction which is in alignment with the orientation of pyramidal neurons at the medial wall. The optimal current direction in our results is approximately 30° rotated.
