Analysis of flow through cylindrical packed beds with small cylinder diameter to particle diameter ratios
(2014)
The wall effect is known to present difficulties when attempting to predict the pressure drop over randomly packed beds. The Nuclear Safety Standard Commission, “Kerntechnischer Auss-chuss" (KTA), made considerable efforts ...
Thermal fluid network model for a prismatic block in a gas-cooled reactor using FLOWNEX
(2015)
Very High Temperature Reactors are complex reactors and various system codes have been developed to design different aspects such as neutronics, thermal hydraulics etc. Flownex is one of the system codes and it has been ...
Numerical analysis of the flow distribution within packed columns using an explicit approach
(North-West University, 2011)
Existing correlations developed to account for pressure drop and velocity distribution
in packed beds are not ideal for beds with low aspect ratios. This study investigated
a method to model flow distribution through ...
CFD modelling of air flow through a finned coil heat exchanger to improve heat transfer and pressure drop predictions
(North-West University (South Africa), 2020)
In the current study, a method of lessening computational expense and model design effort is investigated for finned coil heat exchangers (FCHXs) by using STAR-CCM+ as simulation tool. The simulation model prediction ...
Development of a mixed-flow pump for a small-scale hydro power test facility
(North-West University (South Africa), 2020)
A holistic method for the design of a mixed-flow pump was sought, but was not readily available in open literature. A design and evaluation methodology for a mixed-Flow pump has been developed by making use of open literature ...
Sailplane fuselage aerodynamic optimization using CFD
(North-West University (South Africa), 2020)
In sailplane aerodynamic design, the foremost validation technique applied is computational fluid dynamics (CFD) simulation due to its ability to obtain accurate aerodynamic information without the need for a wind tunnel. ...
The modelling of particle build up in shell–and–tube heat exchangers due to process cooling water
(North-West University, 2013)
Sasol Limited experiences extremely high particulate fouling rates inside shell-and-tube heat exchangers that utilize process cooling water. The water and foulants are obtained from various natural and process sources and ...
Investigation into the coupled 1D and 3D numerical modeling of an air-cooled heat exchanger configuration
(North-West University, 2018)
One dimensional (1-D) systems CFD can be used to simplify the analyses of thermal-fluid problems with complex geometries as it has the capability to provide quick solutions on fluid dynamics such as pressure changes, ...
Aerodynamic analysis and design of a solar powered vehicle using CFD
(North-West University (South Africa) , Potchefstroom Campus, 2016)
The need for solar-powered vehicles is increasing as the threat of depletion of non-renewable energy sources, such as oil, increases. This gives reason for developing electric vehicles powered by renewable energy sources, ...
Analysis of total energy probes for sailplane application
(North-West University, Potchefstroom Campus, 2018)
Sailplane manufacturers who strive to design and build the best competition sailplanes in the world try to outwit their competitors through improved gliding performance. Although significant effort is made to make the ...
