Accounting for porous structure in effective thermal conductivity calculations in a pebble bed reactor
(Atomic Energy Society of Japan, 2009)A proper understanding of the mechanisms of heat transfer, flow and pressure drop through a packed bed of spheres is of utmost importance in the design of a high temperature pebble bed reactor. A thorough knowledge of the ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ... -
Multi–Sphere Unit Cell model to calculate the effective thermal conductivity in packed pebble beds of mono–sized spheres
(Elsevier, 2012)This paper presents a new approach to the calculation of the effective thermal conductivity in packed pebble bed reactors, namely the Multi-sphere Unit Cell model. The model specifically accounts for the porous structure, ... -
Separate effects tests to determine the effective thermal conductivityin the PBMR HTTU test facility
(Elsevier, 2014)Thermal-fluid simulations are used extensively to predict the maximum fuel temperatures, flows, pressure drops and thermal capacitance of pebble bed gas cooled reactors in support of the reactor safety case. The PBMR company ...
