The runner blade-to-blade shear flow turbulent mixing characteristics in the cone of a Francis turbine scale model are investigated by using the 3D PIV Technique. From the experimental flow survey, the periodic component of the instantaneous velocity field ...

The aims of the preliminary study reported in this document were twofold. Firstly, within the context of the application of UHPFRC for the rehabilitation of reinforced concrete structures, to identify the phenomena that require further study with respect t ...
Tracers released into the pelagic, stratified center of lakes, show that interior mixing - based on both mode-related internal shear and higherfrequency internal waves â is extremely weak. After horizontal spreading, the tracers "feel" the local bottom ...
Using the fluorescent dye uranin, tracer release experiments to study the contribution of bottom boundary mixing to diapycnal transport in stratified natural waters were performed in Lake Alpnach (central Switzerland) during 1992-1995. A first experiment i ...
Experimental results on storage and mixing of ten-percent-talin/water ice slurries are presented. For this purpose a system with a storage tank, with a volume of 1000 liters and a mixing device containing three slightly inclined cones, was investigated. In ...

The electronic states in the conduction and valence bands of quantum wires are studied by means of the effective mass hamiltonian and the Luttinger hamiltonian. The band mixing effects due to the wire geometry are fully taken into account by an accurate fi ...
Following several tragic chemical accidents that have occurred in recent years, some directives concerning chemical process safety have been issued. The Seveso directive, for example, requires a precise description of the consequences of a possible chemica ...
Any innovative design of a chem. or biol. reactor has to consider the dynamics of the primary phys. and chem. steps involved in the overall process. For homogeneous highly viscous systems the mixing time is of crucial importance for the product quality. In ...
We report extensive molecular-dynamics-simulation results for binary mixtures of hard spheres for different size disparities and different mixing percentages, for packing fractions up to 0.605, and over a characteristic time interval spanning up to 5 order ...
The present work focuses on the flow characteristics and mixing induced by Sulzer SMRX static mixers. It is obsd. both exptl. and numerically that pressure drop increases linearly with velocity for this mixer type and that, as expected, this effect is ampl ...
