Abstract (sommario):

This study focuses on the optimisation of submerged hollow fibre membrane performance by analysing the role of air sparging on the reduction of membrane fouling. In submerged hollow fibre membranes, rising bubbles have been shown to induce shear, liquid movement and fibre displacement. The interaction between fibre movement induced by bubbling and the microfiltration performance was assessed for various parameters (fibre tightness, fibre length, fibre diameter, air flowrate, nozzle size, and feed concentration). A model feed of yeast suspension and a series of isolated fibres were used. The fi

Polyacrylonitrile (PAN) hollow fibres have been spun by a dry-jet wet spinning technique, using a commercial PAN polymer (Courtelle) redissolved in dimethylformamide (DMF). After failure to produce satisfactory porous hollow fibres from PAN/DMF solutions, a series of studies on the porous substructure of PAN cast films prepared with a variety of additives in the casting solution and at varying temperatures of the coagulation bath were carried out. A porous and flexible PAN cast film was produced when it was precipitated in water at 55 °C with CuSO4 present in the casting solution. Hollow fibre

Abstract (sommario):

Anti-resonant hollow core fibre is a new kind of optical fibre waveguide in which light is trapped in a hollow core surrounded by the capillary formed microstructured cladding. This fibre exhibits high damage threshold, low dispersion and ultra-low nonlinearity with relatively low loss of a few tens of dB/km. Its intrinsic feature of multimode delivery limits the applications with high requirements of single mode transmission. In my thesis, I demonstrate how the design of hollow core fibre can be improved with single mode guidance. S2 imaging measurement was used to analyse the mode content of

The sustainability of a large pilot-scale hollow fibre immersed membrane bioreactor (HF iMBR) has been investigated with specific reference to membrane surface fouling and membrane channel clogging.

A review of mechanically- moved membranes was conducted with a view to exploring a low energy means of sustaining operation through suppressing clogging.

Gas absorption in hollow fibre contactors is being increasingly used due to their enormous surface area/volume ratio. The capability of the hollow fibre membrane modules for the removal of CO 2 and SO2 from a binary gas mixture has been investigated experimentally. Four different modules were used in this study. The membranes in modules one and two were made of microporous polypropylene. The third module was made of non-porous silicone rubber (polydimethylsiloxane) while the latter one was a polyvinylidenefluoride (PVDF) asymmetric hollow fibre membrane.

Abstract (sommario):

Osmotic distillation is a process of removing water from an aqueous solution, driven by water vapour pressure gradient across a hydrophobic membrane. The process occurs at or below ambient temperature and under atmospheric pressure. This research project investigates the osmotic distillation process in hollow fibre modules using hollow fibres PP375, PV375 and PV660 supplied by Memcor Australia. Operating conditions such as temperature, feed concentration and brine cross flow velocity, but not the feed cross flow velocity, were found to have significant effect on the flux.

An investigation of prestressed concrete containing steel fibres as secondary reinforcement to improve performance in shear, flexure and bond is reported. Emphasis is placed on the use of steel fibres in prestresssed extruded hollow core slabs, since these common precast elements have intrinsic difficulty in incorporating traditional secondary reinforcement due to their unique shape and manufacturing method.

Abstract (sommario):

The humble electrically pumped gas laser has undergone little development in its fifty year life span due to the lack of an effective method to confine light within a hollow waveguide of any appreciable length in which an electrical discharge could be contained. New technologies in the field of anti-resonant guiding hollow core fibres present an opportunity to re-invent the gas laser. A recent breakthrough in the field demonstrated that DC pumped glow discharges of a helium and xenon gas mixture could not only be sustained in such a fibre, but also exhibited signs of gain on a number of mid-IR

The use of hollow fibre bioreactors in mammalian cell culture has provided a means by which large populations of viable cells can be grown continuously, for extended periods, in a relatively small volume of vessel. Bioreactors in which one set of fibres are used for nutrient and metabolite exchange from the cell mass are limited by their reliance on an axial flow regime. This pressure mediated flow pattern leads to the formation of nutrient gradients within the cell mass, which occur due to the large diffusional distances present in the growth space, resulting in cell death within the bioreact

Abstract (sommario):

In current water industry, direct-flow hollow fibre filtration is increasingly used as an intermediate or complete water purification technique. Compare to classical crossflow filtration, direct-flow filtration avoids high pressure drop that incurs high energy cost in the feed channel and permits the use of smaller diameter fibres which increases the filtration area per unit volume. Such filtration is achieved by efficiently capping one end of the crossflow device and it is usually operated in dead-end mode with regular intermittent backwash. Direct-flow filtration therefore forms the dominant

Abstract (sommario):

The development of photonic crystal fibre from conventional optical fibre follows a trend in the development of materials, to create composites and structured materials on smaller and smaller scales. In fact the great success of photonic crystal fibre is largely due to the ability to structure it on scales comparable to the wavelength of light. It is this micron size structure that allows the creation of an (out of plane) optical bandgap in silica and allows hollow core fibre to guide light in an air core freeing the guided mode from the properties of bulk silica.

Laminar flow and mass transfer models have been developed to examine performance through axial-flow hollow fibre modules.

However, the hydrophobicity of PLGA results in scaffolds that are poorly wettable, and which, therefore, possess poor mass transfer properties for the delivery of nutrients and the removal of waste.

Abstract (sommario):

This research was a step forward in developing bond strength of CFRP strengthened steel hollow sections under tension loads. The studies have revealed the ultimate load carrying capacity of the CFRP strengthened steel hollow sections and the stress distribution for different orientations of the CFRP sheet at different layers. This thesis presents a series of experimental and finite element analysis to determine a good understanding of the bond characteristics of CFRP strengthened steel hollow sections.
