High Temperature Test Unit Engineering Simulator
Pebble Bed Micro Model Start-up
The PBMM (the world's first closed cycle multi-shaft gas turbine test rig) was developed to demonstrate the operation of a three-shaft, pre- and inter-cooled recuperative Brayton cycle in order to gain a better understanding of its dynamic behavior. The entire cycle was designed, simulated and commissioned with Flownex within 9 months at a cost saving of $48 million.
Pebble Bed Micro Model
Reactor Cavity Cooling System - Steady State
Flow and Heat Transfer in a Packed Bed - Steady State
Flow and 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.
