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 ... -
Comparison between Flownex and CORONA thermal-hydraulic models for a single HTR prismatic fuel assembly
Khoza, S.N.; Du Toit, C.G.; Rousseau, P.G.; Lee, S.N. (ANS (American Nuclear Society), 2016) -
The extraction of the temperature gradient from measured temperature profiles with uncertainty propagation, as applied to the high temperature test unit
Van Antwerpen, H.J.; Rousseau, P.G.; Du Toit, C.G. (SAAM, 2010)This paper highlights the usefulness of applying analytical methods for uncertainty analysis to a least-squares polynomial fit. It also presents an equation to calculate the confidence interval in the slope of a regression ... -
The flow and heat transfer in a packed bed high temperature gas-cooled reactor
Du Toit, C.G.; Rousseau, P.G. (ASME, 2010)Engineers are faced with two major challenges when carrying out the thermal-fluid design of a complex system consisting of many interacting components such as the PBMR power plant. The first challenge is to predict the ... -
Formulation of a unit cell for a thermal-hydraulic systems model of a prismatic fuel block of a high temperature gas-cooled reactor
