Accounting for porous structure in effective thermal conductivity calculations in a pebble bed reactor

Van Antwerpen, W.; Rousseau, P.G.; Du Toit, C.G. (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

Du Toit, C.G.; Van Antwerpen, W.; Rousseau, P.G. (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 ...
