The influence of design parameters on the occurrence of shielding in multi-electrode ESPs and its effect on performance
(Elsevier, 2018)
A numerical model in which OpenFOAM® is used to model the electrostatic field resulting from corona discharge in single-channel wire-plate electrostatic precipitators (ESPs) was applied to systematically study the shielding ...
A review of methods to predict the effective thermal conductivity of packed pebble beds, with emphasis on the near-wall region
(Elsevier, 2018)
The effective thermal conductivity is an important parameter that is representative of the overall heat transfer in a packed bed of spheres. It includes the effects of conduction through the solid material and contact areas ...
Multiobjective design of a line-start PM motor using the Taguchi method
(IEEE, 2018)
This paper investigates the use of the Taguchi method for the design of line-start permanent magnet synchronous motors (LS-PMSMs). To address the inherent limitation of the Taguchi method in solving multiresponse optimization ...
Experimental validation of a rotor delevitation model with quantified severity indicators
(Elsevier, 2018)
This paper presents the experimental validation of BBSim: a non-linear model for simulation of rotor delevitation in an active magnetic bearing system with backup bearings (BBs). The rotor delevitation model’s purposes are ...
Using big data for insights into sustainable energy consumption in industrial and mining sectors
(Elsevier, 2018)
Human activities related to the production and consumption of energy are negatively impacting the environment and need to be addressed by focusing on cleaner production. With this perspective, this study investigates ...
Failure prediction of mine de-watering pumps
(Springer, 2018)
The de-watering reticulation system of a deep level mine requires a network of pumps to pump water from underground to the surface. These de-watering pumps are exposed to extreme operating conditions, which can result in ...
Methods, measures and indicators for evaluating benefits of transportation research
(Taylor & Francis, 2018)
The purpose of this article is to provide updated information by identifying and discussing methods, measures and indicators for evaluating benefits appropriate for transportation-related research facilities/programmes. ...
A survey of the state of condition-based maintenance (CBM) in the nuclear power industry
(Elsevier, 2018)
Condition-based maintenance (CBM) involves undertaking maintenance activities based on the health of the system. CBM has found useful applications in many industries. This paper presents a survey on the state of condition-based ...
Influence of additives on the devolatilization product yield of typical South African coals, and effect on tar composition
(SAIMM, 2018)
South African coal is mainly used for electricity generation by means of
pulverized fuel combustion and liquid fuels production via indirect
gasification technology and Fischer-Tropsch synthesis. In order to expand
the ...
Green coal development for application in fixed-bed catalytic gasification
(SAIMM, 2018)
A novel ‘green coal’ product formulation has recently been developed and
the utilization concept tested at the North-West University coal research
laboratories. Hydrothermal liquefaction was used to produce bio-oil ...
