The axial temperature profile of a packed bed is often measured by thermocouples placed
either directly in the bed or inside a thermowell centered in the reactor tube. Quantifying the …

The flow behavior of the powder layer significantly affects subsequent dynamic behavior and
final quality of the parts fabricated via powder bed-based additive manufacturing. High …

Cylindrical particles are widely employed in chemical engineering when a high surface area
is necessary for process intensification. However, reliable information about the orientation …

This paper provides new experimental data on the orientation of cylindrical particles
(defined as angle φ between the particle's axis and the line parallel to the column axis) in …

Packed bed reactors of non-spherical particles are widely used in chemical industry with the
aim to obtain a high active surface area and achieve a homogeneous flow. Despite this, little …

Achieving our decarbonisation goals for the maritime transport sector requires the bulk
production of liquid hydrocarbon fuels, suitable for the existing infrastructure, such as …

This work develops an approach to identify the suitable representative volume (unit cell) that
captures fluid dynamics in beds packed with spheres or cylinders with adt/dp≤ 10, by …

We consider packed-bed reactors with dielectric beads in a two-dimensional channel
geometry, apply an electric field perpendicular to the walls, and explore numerically the …
