FLOW & HEAT TRANSFER IN A PACKED BED – TRANSIENT

This case study demonstrates the transient simulation of the heat transfer through a packed bed with no forced convection. This case study is applicable to packed pebble beds where only natural convection is present in the bed due to a heat source on the inside of the bed and a heat sink on the outside of the bed.

"The ability to model the correct transient removal of the heat through the bed will be important for predictions of when a nuclear pebble bed reactor will become recritical after the forced cooling flow was stopped or whether the bed will be able to remove the heat without any active heat removal systems present."
