CFD analysis of the heat transfer from a self-launch sailplane radiator
(North-West University (South Africa), 2019)A self-launch sailplane is an aircraft equipped with a retractable engine/propeller combination which can take-off on its own power. The engine can also be used to extend flights if necessary. The engine-driven propeller ... -
Comparison of heat transfer models at the pebble, gas and reflector interface in the PBMR
(North-West University, 2010)It is a great challenge in the design of the PBMR to accurately predict gas flow and heat transfer in the reactor. Understanding the heat transfer at the core-reflector interface in particular is a very important aspect ... -
Determination of a safe distance for atomic hydrogen depositions in hot-wire chemical vapour deposition by means of CFD heat transfer simulations
(Tech Science Press, 2020)A heat transfer study was conducted, in the framework of Computational Fluid Dynamics (CFD), on a Hot-Wire Chemical Vapour Deposition (HWCVD) reactor chamber to determine a safe deposition distance for atomic hydrogen ... -
A FEM model for microwave absorption and heat transfer in a microwave combination washer dryer
(IEEE, 2013)Applications for the use of microwaves reach far and wide in various industries. Commonly known is the use of microwaves to heat foodstuffs. Research and development conducted in the development of a microwave combination ... -
The flow and heat transfer in a packed bed high temperature gas-cooled reactor
(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 ... -
An integrated thermal-hydraulic system CFD model of a prismatic block HTR core using Flownex
(North-West University (South Africa), Potchefstroom Campus, 2019)The active core of a prismatic high temperature reactor (HTR) consists of standard fuel, reserve shutdown and control blocks which must be maintained within a safe operating envelope. The fuel blocks are coupled to the ... -
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 ... -
A numerical analysis of laminar boundary layer flow of a jeffrey fluid past a vertical porous plate in the presence of thermal radiation and chemical reaction
(Pushpa, 2019)This work deals with the study of the flow of a Jeffrey’s fluid past a vertical porous plate in the presence of thermal radiation and chemical reaction. A similarity transformation is used to transform the partial differential ... -
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
(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 ... -
The optimal hydraulic diameter of semicircular and triangular shaped channels for compact heat exchangers
(North-West University, 2010)All heat pump cycles have one common feature that connects them to one another; this feature is the presence of a heat exchanger. There are even some heat–driven cycles that are completely composed of heat exchangers, every ...
