1D and 3D simulation of a water cooled reactor cavity cooling system experimental facility
(North-West University (South Africa)., 2021)The fourth-generation nuclear reactors have many safety features, including the reactor cavity cooling system (RCCS). This system is intended to remove decay heat from the reactor cavity. Designs exist for both air-cooled ... -
Analysis of the pressure drop through structured packed beds
(North-West University (South Africa), 2020)Accurately analysing the pressure drop over structured packed beds is of great importance to certain reactor designs, such as the Pebble Bed Modular Reactor (PBMR). In previous studies, the High Pressure Test Unit (HPTU) ... -
Analysis of the radial, axial and tangential porosity variations of packed beds of spheres
(North-West University (South Africa)., 2022)The porosity of a packed bed of spherically shaped particles influences different thermo-hydraulic phenomena in such packings. An understanding of the porous structures in such packings is therefore important for the design, ... -
Investigation into different 1D/3D thermal fluid co-simulation methodologies as applied to HTR system configurations
(North-West University (South Africa)., 2022)The current PhD research focuses on the investigation into different 1D/3D thermal fluid co-simulation methodologies as applied to HTR system configurations. For the modelling and simulation of complex systems, 1D/3D ... -
Simulation of the heat and coolant flow for a PMR200 reactor using a network approach in Flownex
(North-West University (South Africa)., 2022)The VHTR (Very High-Temperature Reactor) Prismatic block reactor is one of the reactor designs considered in the range of 4th Generation Reactors which are under development today. The heat generated by the gas-cooled ... -
Suction recirculation mitigation in a double-suction centrifugal pump
(2021)Suction recirculation in centrifugal pumps operating at o˙-design conditions is an eventual reality for all centrifugal pumps. Various types of modifications to both the pump impeller and/or volute have been implemented ... -
The zonal approach applied to the simulation of the radiative heat transfer in a packed pebble bed
(North-West University (South Africa), 2020)The Fukushima Daiichi Nuclear Disaster highlighted the importance of nuclear safety and the importance of modeling a nuclear reactor under diverse conditions. Applied to pebble bed reactors, these diverse conditions include ...
