X-ray sources are developing rapidly and their coherent output is growing correspondingly.
The increased coherent flux from modern X-ray sources is being matched with an …

Flow visualization and characterization of multiphase flows have been the quest of many
fluid mechanicians. The process is fairly straight forward only when there is good optical …

A novel fluorescence microscopy technique for visualizing the transport of liquid water in
unsaturated hydrophobic fibrous media has been developed and is applied to the gas …

Advances in microfluidic and nanofluidic technologies have been paralleled by advances in
methods for direct optical measurement of transport phenomena on these scales. A variety …

A unique flow visualization facility, based on X-ray imaging, has been developed to study,
characterize, and measure various flow characteristics in large vertical systems that have …

In recent years, several techniques have been introduced that are capable of extracting 3D
three-component velocity fields in fluid flows. Fast-paced developments in both hardware …

An in-situ measurement technique to determine the rheology of a fluid based on the
experimentally measured velocity profile of a flow in a mini-channel is introduced. The …

The quasi-stable sheet cavitation produced in a small Venturi channel is investigated using
a fast synchrotron x-ray imaging technique aided with conventional high speed …

The use of X-ray flow visualization has brought a powerful new tool to the study of
multiphase flows. Penetrating radiation can probe the spatial concentration of the different …

When granular materials flow, the constituent particles segregate by size and align by
shape. The impacts of these changes in fabric on the flow itself are not well understood, and …
