Hydraulic modeling of a confined gas recirculation mixing system for a CSTR anaerobic digester
(2016)ENGLISH ABSTRACT: Hydraulic numerical rnadelling and experimental werk was used to develop a mixing system, that is able to satisfy the biologica! requirement of micro bacteria and create a homogeneaus salution inside ... -
Performance characterisation of a separated heat-pipe-heat-recovery-heat-exchanger for the food drying industry
(2016)ENGLISH ABSTRACT: This paper presents the performance evaluation of a separated-HPHRHE for use in the food processing industry. The outside heat transfer coefficients were obtained by passing hot air over a HPHE filled ... -
Theoretical modelling and experimental verification of the heat transfer behaviour of a water-charged closed-end loop pulsating heat pipe
(2001)ENGLISH ABSTRACT: In this paper the theoretical modelling of a Pulsating Heat Pipe (PHP) is presented. In this particular model the flow of the working fluid is modelled as discrete liquid plugs moving back and forth because ... -
Investigation of two-stage electrostatic precipitation for silver removal from a helium stream
(2010)ENGLISH ABSTRACT: In high temperature gas cooled nuclear reactors various unwanted particles have been found to plate out onto the surfaces of the primary cicuit components. A simple deterministic deflection model is ... -
Use of passive cooling systems in generation IV nuclear reactors for core decay heat removal and containment cooling
(2011)ENGLISH ABSTRACT: The Pebble Bed Modular Reactor (PBMR) concept evolved from a German high temperature helium-cooled reactor design with ceramic spherical fuel pebbles. The removal of parasitic heat between the reactor ... -
Numerical modelling of a loop-type heat pipe suitable for the reactor cavity cooling system of the Pebble Bed Modular Reactor
(2011)ENGLISH ABSTRACT: The feasibility of a closed loop thermosyphon for the Reactor Cavity Cooling System (RCCS) of the Pebble Bed Modular Reactor has been the subject of many research projects. One of the difficulties identified ... -

Experimental investigation and numerical simulation of instabilities in a multi-parallel channel two-phase natural circulation system
(2015)ENGLISH ABSTRACT: In the present study, two-phase natural circulation flow in a multi-parallel channel system is investigated using experimental and numerical modelling. The experimental model consisted, essentially, of ... -
Small scale organic Rankine cycle for solar applications
(2015)ENGLISH ABSTRACT: The global demand for energy has risen dramatically in recent years and the cost of electricity has risen considerably. Local electricity sales prices followed the global trend, increasing by an average ... -
Deflection of Ag-atoms in a magnetic field
(2011)ENGLISH ABSTRACT: An apparatus that generates and deflect silver-109 atoms with an inhomogeneous and homogeneous magnetic field was constructed. The experimental results found using this apparatus were used to make a ... -
Thermally driven natural circulation water pump
(2015)ENGLISH ABSTRACT: The water utilized by passive air-conditioning systems in buildings is typically required at higher elevations. The thermally driven natural circulation water pump (TDNCWP) is a passively driven pumping ... -
Thermal modelling of a heat block and heat sink connected by heat pipes using finite element methods
(2001)ENGLISH ABSTRACT: This article considers the heat transfer between a simple heat block and a heat sink, using heat pipes as the energy transport medium. Both the heat block and heat sink are made from carbon steel. The ... -
The development of a 1D-transient simulation model of a CO2 refrigeration system
(2016)ENGLISH ABSTRACT: Refrigeration is a highly essential part of modern day living. The drive for alternative cleaner technologies has renewed interest in designing refrigeration systems using CO2 as refrigerant. The goal of ... -
The design and testing of a secure surface tension driven water pump
(2015)ENGLISH ABSTRACT: Water pumping is essential for life as we know it. The drive for alternative energies together with the need for water pumping has inspired the construction of a surface tension driven water pump (STDWP). ... -
Silver ion generation, deflection and deposition in vacuum
(2011)ENGLISH ABSTRACT: The potential problems arising during the operation of a pebble bed modular type reactor has stimulated a number of research avenues in different fields. This study presents results of a first approach method ... -
Waste to resource process chain strategies for global manufacturers
