| Abstract: | The packing behaviors of pebble bed in blanket were investigated by packing experiment and discrete element modeling. The packing behaviors of cylinder mono-sized pebble beds show that the average packing factor is gradually increased with increase of the diameter ratio of the bed to pebbles. The experimental and simulated results of cylinder mono-sized pebble beds are in good agreement. Using binary-sized pebble packing and increasing the size ratio of binary pebbles can increase the packing factor of pebble bed, significantly. For binary-sized pebble bed, the average packing factor increases first and then decreases with the increase of the large pebble volume fraction. The maximum value is achieved when the larger pebble volume fraction is about 60%~80%. By optimizing the filling process of the pebble bed, the packing factor of the binary-sized pebble bed has reached 0.8, but the uniformity of the binary-sized bed is poor. |
