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 ...
Using an effective viscosity to account for the effect of the walls on the pressure drop through an annular packed bed
(ASME, 2009)
The question arose whether the correlation for the pressure drop prescribed for cylindrical pebble bed reactors by the Nuclear Safety Commission (KTA) of Germany could still be applied to the proposed annular configuration ...
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 ...
The global galerkin finite element method as applied to the 1d beam equation: a systems approach
(SAAM, 2006)
The paper focuses on the finite element solution of the fourth-order differential for an EulerBernoulli beam. In this approach the point point loads and concentrated moments are treated in a natural way as part of the ...
