Finite element density functional calculations for light molecules using a cusp factor to mitigate the Coulomb potential
(EDP Sciences, 2019)Finite element calculations have been performed in Cartesian coordinates using the density functional approach for a number of small molecules. In order to aid convergence of the orbitals and total energies a suitable cusp ... -
Finite element modal analysis for a cooler fan support structure
(SACAM, 2016) -
First principles study of single and multi-site transition metal dopant ions in MoS2 monolayer
(Elsevier, 2019)Using first-principles calculation, a systematic study on the effect of transition metal (TM: V, Cr, Mn, Fe, Co, Ni) dopant atoms in the MoS2 monolayer as potential spintronic, catalytic and optoelectronic materials were ... -
First-principle studies of ferrimagnetic double perovskite Ca2FeMoO6 compound
(Springer, 2019)Using first-principle calculations, the structural, electronic, and magnetic properties of the Ca2FeMoO6 double perovskite compound is investigated. Different spin-ordering: ferrimagnetic (FiM), ferromagnetic (FM), and ... -
Flight controller and low-cost test environment for a simulated helicopter
(IFAC, 2014)In this paper, optimal linear control techniques are utilised to control a radio-controlled helicopter (30 size) in the AeroSIMRC simulation environment. A grey-box time-domain system identification method is used to ... -
Flocculant types and operating conditions influencing particles settling rates in feed water used at a coal power plant
(Desalination Publications, 2019)South Africa is a semi-arid country with an average rainfall less than half of the average rainfall worldwide. From the country limited water resource, 2%–3% of the water is used in energy generation. Thus the water ... -
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 ... -
Flow over a glider canopy
(Royal Aeronautical Society, 2014)In order to minimise drag, the front part of most modern glider fuselages is shaped so that laminar flow is preserved to a position close to the wing-to-fuselage junction. Experimental investigations on a full-scale JS1 ... -
Fluidized bed gasification of selected South African coals
(South African Institute of Mining and Metallurgy, 2010) -
A flux splitting method for the Euler equations
(Elsevier, 2014)The solution of the Euler and Navier–Stokes equations was the focus of this research. As with methods such as the AUSM-family, this work further attempted to construct an explicit upwind method that combines both simplicity ... -
Fly ash resistivity profiling for South African coal fired power stations
(David Publishing, 2013)Particulate emission is a major problem in industrial processes, mainly power plants that make use of coal as a primary source of energy. Stringent emissions limits, set by government organisations requires industries to ... -
Four novel methods for the harvesting of micro-algal biomass
(ETA-Florence Renewable Energies, 2011)The harvesting of micro-algal biomass is one of the most inefficient and costly steps in the whole biomass-to-liquids (BtL) value chain. Harvesting costs may contribute between 20–30% of the total cost of microalgal BtL ... -
Framework for effective additive manufacturing education: a case study of South African universities
(Emerald, 2019)Purpose In this era of Fourth Industrial Revolution, also known as Industry 4.0, additive manufacturing (AM) has been recognized as one of the nine technologies of Industry 4.0 that will revolutionize different sectors ... -
Frequency dependent impedance model for heteropolar magnetic bearings
(Elsevier, 2015)Accurate analytical models are fundamental to design and optimise high performance magnetic bearings. Understanding the bearing’s dynamic behaviour over its operational envelope is essential to this task and is performed ... -
Fuel allocation and lockout system
(IEEE, 2018)In transport and Logistics business with the fierce competition, avoiding fuel theft through monitoring and management is a major concern in Africa. With the steadily increase in fuel price, fuel theft and fraud poses a ... -
Fuel ethanol production from sweet sorghum bagasse using microwave irradiation
(ETA-Florence Renewable Energies, 2013)Sweet sorghum is a hardy crop that can be grown on marginal land and can provide both food and energy in an integrated food and energy system. Lignocellulose rich sweet sorghum bagasse (solid left over after starch and ... -
Fuel not food: towards sustainable utilization of gutter oil
(Taylor & Francis, 2017)Waste cooking oil is discarded into sewage and waste bins in various developing countries. In China, the discarded oil is scooped illegally from drains by smugglers. After collection, the obtained waste oil is reprocessed; ...
