Abstract:

A hydrokinetic coil pump (HCP) is described by its name. It is a coil pump driven by the kinetic energy in flowing water. The hydrokinetic energy is converted into mechanical energy by means of a paddle-wheel. The coil pump makes up part of the paddle-wheel and together is called a HCP. The HCP floats in a stream of flowing water while tethered to the bank. The focus of the study was to identify and analyse the factors influencing the HCP. The HCP was then optimized for rural application. Data acquisition took place through experimentation on a full scale experimental platform according to a c

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2009.<br>The aim of this study is to analyse the operation of a wind-electric pumping system (WEPS) as an alternative to conventional mechanical wind pumps for application in stand-alone water-pumping schemes. The steady-state as well as the dynamic operation of such a system is analysed. Through these analyses, practical guidelines are given in the design and sizing of the different system components to ensure efficient and reliable operation.

Abstract:

This thesis is concerned with the dominant leakage characteristics of an axial piston pump. Results have been obtained from a combination of analysis, Computational Fluid Dynamics (CFD) and experimental work, and have added to existing knowledge in this field. The measurement of slipper leakage within an axial piston pump is impossible due to additional leakage from the pistons and between the cylinder barrel and port plate. It may only be determined by analysis and this aspect has been studied via a new CFD simulation. Further progress has been made experimentally on slipper leakage. A new te

The modelling, design, construction and experimental testing of a carbon-ammonia adsorption heat pump is presented. The main objective of the research was to design, manufacture and test an adsorption generator with low thermal mass and high power density. The adsorption generator developed was a stainless steel, nickel brazed plate heat exchanger. Computational modelling of the generator with thermal wave and multiplebed cycles revealed that multiple-bed cycles give a superior trade-off between efficiency and power density. Further modelling was carried out to evaluate the performance of the

A lack of suitable data, in the form of the machine performance characteristics, during the early stages of a hydro-power station's development led to the investigation of alternative sources of performance characteristics, not based on the testing of a hydraulically similar model turbine. Two methods of obtaining turbine performance characteristics were developed, one based on the published performance characteristics of typ

Most patients diagnosed with End Stage Renal Disease (ESRD) undergo hemodialysis. Traditional hemodialysis treatment requires patients spending three to five hours every other day while yielding the high waste level accumulated between treatments. These limitations in the current technology have spurred the development of a portable renal replacement system. The portable system will not only free the patients from visiting the clinic but also allow more frequent treatment that will lead to lower average waste level.

Human-machine interfaces influence both operator effectiveness and machine efficiency. Further immersion of the operator into the machine’s working environment gives the operator a better feel for the status of the machine and its working conditions. With this knowledge, operators can more efficiently control machines. The use of multi-modal HMIs involving haptics, sound, and visual feedback can immerse the operator into the machine’s environment and provide assistive clues about the state of the machine.

In this thesis an analysis is developed to predict the leakage and dynamic characteristics for circumferentially grooved turbulent annular seals used in turbopumps. The flow in the groove is modelled using turbulent shear layer theory and an entrance loss model is applied at the inlet and land regions of the seal. The governing equations are derived using Hirs’ turbulent lubrication theory. The equations are expanded to yield zeroth and first order perturbation equations for small rotor displacements about a centered position.

Abstract:

This paper deals with the application of speed variable pumps in industrial hydraulic systems. The benefit of the natural feedback of the load torque is investigated for the issue of condition monitoring as the development of losses can be taken as evidence of faults. A new approach is proposed to improve the fault detection capabilities by tracking the changes via machine learning techniques. The presented algorithm is an art of adaptive modeling of the torque balance over a range of steady operation in fault free behavior. The aim thereby is to form a numeric reference with acceptable accura
