Analysis of the porous structure of packed beds of spheres using computed X-ray tomography
Du Toit, C.G.; Rosslee, P.J. (SAAM, 2012) -
CFD analysis of thermal dispersion in a structured packed bed
Vermaak, H.J.; Du Toit, C.G. (SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
The global galerkin finite element method as applied to the 1d beam equation: a systems approach
Du Toit, C.G. (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 ... -
Global Galerkin finite element solution of the fourth-order Euler- Bernoulli beam equation
Du Toit, C.G. (SAAM, 2010) -
Local rise of total pressure in viscous flow through cylindrical packed beds with spherical particles
Van der Merwe, W.J.S.; Du Toit, C.G.; Kruger, J.-H. (SAAM, 2014) -
Modelling the superficial velocity distribution inside an annular packed bed
Reyneke, H.J.; Du Toit, C.G. (SAAM, 2010) -
Numerical simulation of break flows occurring in the reactor cavity cooling system of a very high temperature reactor using a system CFD approach
Du Toit, C.G.; Rousseau, P.G.; Jun, J.S.; Kim, M.-H. (ANS (American Nuclear Society), 2016)To avoid accidents due to human error or the failure of components, the reactor cavity cooling system (RCCS) of a high temperature reactor must be able to operate naturally or passively safe. The system under consideration ... -
A numerical study to investigate the effect of inlet Reynolds number on the thermal-fluid phenomena in the supercritical carbon dioxide-cooled pebble bed reactor
Latifi, Masoumeh Sadat; Du Toit, C.G. (Springer, 2019)This paper presents a numerical investigation into thermal–fluid phenomena in a supercritical carbon dioxide-cooled pebble bed reactor (SCPBR) core under steady state using computational fluid dynamic. In this study, a ... -
Simulation of natural convective flow in an experimental reactor cavity cooling system facility
Niemand, P.; Du Toit, C.G.; Tak, N.I.; Kim, M.H. (SAAM, 2016) -
Simulation of suction recirculation in double suction centrifugal pumps
Van der Walt, J.P.; Kruger, J.-H.; Du Toit, C.G. (SACAM, 2018)Part-load operation conditions of a centrifugal pump will impose potentially strenuous effects on the operation and reliability of the turbomachine in question due to the risk of suction recirculation. Suction recirculation ...
