The pebble bed high temperature gas-cooled reactor is a promising generation-IV reactor,
which uses large fuel pebbles and helium gas as coolant. The pebble bed flow is a …

Large amounts of high-temperature solid granular (HTSG) materials are produced
throughout the world in metallurgy and building materials industries whose activities are …

Beverloo's law describes the flow rate of grains discharging from hoppers, where the
assumption of a free-fall arch (FFA) is very useful in understanding the physical picture of …

Prediction of the time-related traits of pebble flow inside pebble-bed HTGRs is of great
significance for reactor operation and design. In this work, an image-driven approach with …

The pebbles' movement in the pebble beds of 10 MW high-temperature gas-cooled test
reactor (HTR-10) presents as a kind of circulating quasi-static dense pebble flow. The mixing …

The pebble size is one of the factors affecting the flow characteristics of pebble-bed HTGRs.
The binary-sized circulating pebble flow is investigated from the perspective of flow …

Here the influence of wall frictions on the hopper flows was carefully studied. Up to 500,000
spheres discharged from two-dimensional and three-dimensional hoppers were simulated …

Understanding pebble flow characteristics and residence time distribution is essential for
reactor design, fuel burnup estimations, and safety analysis of High-Temperature Gas …

The current work analyzes the radial and axial distributions of void fraction of a pebble bed
high temperature reactor. A three-dimensional pebble bed corresponding to our test facility …

Pebble flow uniformity and stagnation characteristics are very important for the design of
pebble bed high temperature gas-cooled reactor. Pebble flows inside some specifically …
