Case study for evaluating benefits of pavement research: final results
(The National Academies of Sciences, Engineering, and Medicine, 2013)
Heavy-duty pavement innovations developed through research for a major rehabilitation project in California were evaluated. The performance benefits of the innovations were examined, and the economic benefits from ...
Case study: the effects of a variable flow energy saving strategy on a deep-mine cooling system
(Elsevier, 2013)
Cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water to the mine as well as cooling for mine ...
Prototype super-capacitor photovoltaic streetlight with xLogic SuperRelay functionality
(IRET (Institute of Research in Engineering and Technology), 2013)
In this paper, the authors present and discuss the
design of a prototype super-capacitor photovoltaic (PV)
streetlight with xLogic SuperRelay (PLC) functionality.
Deep-cycle batteries used in solar electrical systems, ...
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 ...
Energy management by means of fault conditions on active magnetic bearing systems
(IRET (Institute of Research in Engineering and Technology), 2013)
This paper presents the use of fault conditions on
active magnetic bearing (AMB) systems as an energy
management tool to improve the operation of AMB systems.
Fault conditions on AMB system are broadly classified ...
Stepwise global sensitivity analysis of a physics-based battery model using the Morris method and Monte Carlo experiments
(Elsevier, 2019)
Physics-based battery models can be very complex and require careful experimental validation, but yield greater insights into the internal processes and their interactions than other cell modelling approaches. The complexity ...
Structural analysis of chars generated from South African inertinite coals in a pipe-reactor combustion unit
(Elsevier Science, 2011)
An inertinite-rich medium rank C bituminous South African coal was utilized to generate chars in a pipe-reactor combustion unit. This unit generates chars at atmospheric pressures and temperature was controlled with N2 to ...
An integral CFD approach for the thermal simulation of the PBMR reactor unit
(Elsevier, 2011)
A CFD method was developed to conduct integral thermal reactor analysis for the complete Reactor Unit of the Pebble Bed Modular Reactor (Pty) Ltd (PBMR). The requirement was however also to include very detailed aspects ...
The random pore model with intraparticle diffusion for the description of combustion of char particles derived from mineral- and inertinite rich coal
(Elsevier Science, 2011)
An investigation was undertaken to determine the applicability of the random pore model with intraparticle diffusion for the determination of the reaction kinetics for the combustion of chars particles derived from coals ...
