Measurement of Vertical Voidage Distribution in Powder Packed Bed Using X-ray Micro Computed Tomography-Comparison between Piston Compression and Centrifugal Compression-

X-ray micro-computed tomography

Micro-computed tomography (μCT) has been successfully used to study the cardiovascular system of mouse embryos in situ. With the use of barium as a suitablecontrast agent, blood vessels have beenimaged and analysed quantitatively such asblood volume and vessel sizes on embryosof ages 14.5 to 16.5 days old. The advantageof using this imaging modality is that it hasprovide...

X-ray computed tomography of packed bed chromatography columns for three dimensional imaging and analysis.

Physical characteristics critical to chromatography including geometric porosity and tortuosity within the packed column were analysed based upon three dimensional reconstructions of bed structure in-situ. Image acquisition was performed using two X-ray computed tomography systems, with optimisation of column imaging performed for each sample in order to produce three dimensional representation...

Quantification of eggshell microstructure using X-ray micro computed tomography

1. X-ray microcomputed tomography can be used to produce rapid, fully analysable, three-dimensional images of biological and other materials without the need for complex or tedious sample preparation and sectioning. We describe the use of this technique to visualise and analyse the microstructure of fragments of shell taken from three regions of chicken eggs (sharp pole, blunt pole and equatori...

Quasi-static Indentation and Compression after Impact Damage Growth Monitoring Using Microfocus X-ray Computed Tomography

1 Introduction The susceptibility of carbon fibre-polymer matrix composites to low velocity impact damage has a direct effect on the residual in-plane compressive strength [1]. Whilst the general understanding of damage caused by impact and post-impact compression is understood from studying failed specimens, the damage evolution process is still not well understood. This is largely due to the ...

Measurement of Liquid Velocity and Liquid Distribution in a Packed Bed Using Electrical Resistance Tomography
